1 Week Pregnant Symptoms – It’s Early Signs of Pregnancy


Are you anxious to get pregnant, but has your period just arrived? Do not be discouraged. This is a message from nature that your body is preparing for a future pregnancy. In two weeks, the ovum will be released by the ovaries and, if all goes well, it will be fertilized by the spermatozoon. From there, yes, you will be officially pregnant. As it is planned to become pregnant, a tip is to start taking folic acid supplements, an essential vitamin for the development of the baby‘s nervous system, which is much more effective when taken before prenatal care.

Week 1 – Gesture

If you have menstruation regulated, the first day of flow is considered as the so famous “date of the last menstruation”. Thereafter, the number of weeks of gestation is calculated. Why is it important? Basically, for 3 reasons:

  1. the exact day of ovulation and fertilization is difficult to pinpoint;
  2. some months of pregnancy will take more than 30 days;
  3. the date becomes a time indication for adopting the “obstetric” reference age.

With pregnancy confirmed, the best thing to do is schedule a medical appointment as soon as possible to start prenatal care.

Why does the count start now?

You must be confused: you are not pregnant yet and the count has begun. Is that so. Because women hardly remember the exact date of conception, doctors chose an easier way to do the math. To avoid errors, gestation is calculated from the first day of the last menstrual period. Thus, the baby, according to this formula universally accepted, is expected to between 280 and 286 days, or 40 weeks, from that date. For women with very irregular menstrual cycles, obstetricians recommend an ultrasound examination about four weeks after the suspected pregnancy. At this stage, the physician, through the formation of the gestational sac, can evaluate the probable date of delivery.

Growth and Development

We explain to you how your body develops in the first week of pregnancy and how your baby is growing. Let us help you clarify all your doubts.

The magic begins. The male cell, the sperm , fertilized the egg , the female cell. The fertilized egg begins to divide only one day after fertilization. This division will last for several days until forming a ball of cells called blastocyst. After five days, the cells begin to separate into two groups. The outer cells form what will be the placenta and the interiors will form the embryo. The embryo begins to travel through the fallopian tubes, and after seven days arrives at the uterus where it will remain for nine months.

My body at 1 week of pregnancy

As happens every month, your body is preparing to receive a new life. Estrogen causes the uterus to be covered by a thick layer of tissue, well watered. The increased release of progesterone prepares the uterus to support a possible fertilized egg. At the same time, in the ovaries, eggs mature into the follicles, which are pouches filled with fluid. In this short period of preparation of the body, conception can occur when a sperm reaches the egg.

The first typical sign of pregnancy is the menstrual delay. Although absence of menstruation is an obvious symptom of pregnancy, many women have other symptoms that indicate the presence of what will be a baby. The fatigue , sleep, more sense of smell, increased breast tenderness, nausea and even state changes of mind are some of the symptoms that indicate pregnancy . Hormonal variations begin , which is reflected in your emotional state. You may feel much more irritable, nervous and moody … Do not worry, your body begins to prepare.

It’s quite possible that even before you confirmed your pregnancy, you had noticed something different in your breasts. This change – which may be in the form of increased sensitivity or even pain – is actually one of the first symptoms of pregnancy .

Here’s a tip: if you maintain intercourse on ovulation day or soon after, the likelihood of being a boy is greater. But if it is one or two days before ovulation, the greater probability is to be a girl.


It is possible, even before you know that you are pregnant, that you begin to notice some changes in your body. Some women feel “strange” but are unable to explain what is happening to them. It is natural that arise fears at the time that the test of pregnancy is positive. Do not worry, you should make sure everything is going well. Be positive, and be aware that your body will start to change. Feeling pressure in the pelvis and hips or an increased urge to urinate are some of the symptoms you may begin to notice in the first few weeks of pregnancy.

More Questions

How can I tell if I’m pregnant after 1 week?

Have you had unprotected sex and are you now full of doubts about the possibility of getting pregnant?

What to do now? What is the next step? How can you tell if you are pregnant? How long should you wait to take a pregnancy test?

It is now fairly easy for any woman to find out if she is pregnant. There are pregnancy tests that can be purchased at any pharmacy and at affordable prices.

  • Classically the diagnosis of pregnancy can be done in two ways:
  • Blood or urine dosage of the hCG hormone (Beta-hCG).
  • Ultrasonography of the uterus.
  • Any other diagnostic method other than the above two can not be considered suitable.

What is hCG?

HCG, also called human chorionic gonadotrophin, is a hormone that begins to be produced as soon as the embryo is implanted in the uterus. As pregnancy progresses, increasing levels of hCG are being produced and released into the mother’s bloodstream, which allows detection through blood or urine tests (part of the hormone is filtered through the kidneys and excreted in the urine).

Beta-hCG is a fraction of the hCG molecule that can also be used for dosing. Both hCG and Beta-hCG can be used for the diagnosis of pregnancy.

Can I rely only on the symptoms to diagnose a pregnancy?

No. The typical symptoms of pregnancy, such as menstrual delay, nausea, swollen breasts, increased abdominal volume, cravings, etc., serve only as an alert for the possibility of an ongoing pregnancy. This group of signs and symptoms are non-specific and many women who are not pregnant can present them.

In addition, many pregnant women may not have any symptoms for several weeks to months in some cases.

Therefore, a pregnancy based on signs and symptoms can not be discounted or confirmed.

Is there any reliable home test to diagnose a pregnancy?

No. Urine boil test, chlorine test, bleach, needle, or any other homemade tip does not serve as an alternative for the diagnosis of pregnancy. The only reliable methods are the blood or urine dosage of beta-hCG or abdominal ultrasonography.

If I’m pregnant and touched my uterus can I feel anything?

No. The uterus begins to change at the 4th week of gestation, but it is impossible for a lay person to be able to identify these changes. In fact, even when the examination is done by a doctor it is possible to state with certainty that there is an initial pregnancy in progress.

I had unprotected sex yesterday, can I tell if I got pregnant?

No. The hCG only begins to be produced when the embryo is implanted in the uterus. Because the ovum is fertilized in the fallopian tubes, it still needs to travel to the uterus for pregnancy to actually establish itself. This trip takes an average of 7 days. And even after implantation it is necessary to wait a few more days for the amount of hCG produced to be sufficient to be detected through blood or urine tests.

Another relevant fact is that fertilization does not always occur on the day of sexual intercourse. Sperm can remain alive in the female reproductive tract for up to 7 days waiting for the egg to appear, which means that fertilization can occur only one week after the sexual act. In these cases, implantation in the uterus only occurs 14 days after the couple has had intercourse

So whether you’re anxious, whether you’ve neglected yourself and not used a contraceptive method, or because you very much want to have a child, it’s no use getting out of pregnancy testing out of time, because you have to give them time to be positive.

What is the best pregnancy test: blood or urine?

Blood tests are more reliable than urine tests. In general, even when the urine test is positive, we suggest pregnancy confirmation through a blood test or an ultrasound.

How long should I wait to take the pregnancy test?

The signal to take the pregnancy test is the menstrual delay. Current Beta-hCG detection techniques allow the test to be positive with only one day of menstrual delay. However, since the hormone concentration is still very low at this stage, it is possible to have a false negative, especially in the pharmacy urine test, which is less sensitive than the laboratory blood test.

So if you have a strong suspicion of being pregnant but the first pregnancy test was negative, wait another 5 to 7 days and repeat it. HCG values ​​usually double every 2 days; after a week they will certainly be very high.

From how many days can be considered delayed menstruation?

If you have an extremely regular and predictable menstrual cycle, a day of menstrual delay is already relevant. On the other hand, if your menstruation comes with different intervals every month, even 5 days late can be perfectly normal. Therefore, there is no universal definition for menstrual delay. Some authors say 5 days, another 10 days and some suggest that menstruation should only be considered late after 15 days. In general, the most accepted definition of delayed menstruation is when menstruation does not appear after the menstrual cycle completes 35 days.

However, from the diagnostic point of view of pregnancy, if you are trying to get pregnant, from 1 or 2 days late, you can already take the pregnancy test. If the first one is negative and the menstruation does not continue, wait 5 days and repeat the test.

Can I take the pregnancy test before I have a menstrual period?

It is not ideal, because the risk of false negative is very great. Usually, menstruation arises 14 days after ovulation; as the fertilized ovum takes a week to reach the uterus, if you take the test before the expected date of menstruation, the embryo may have just implanted into the uterine wall and the production of hCG may still be very small, below the ability of the examination.

Is the pharmacy pregnancy test reliable?

Yes, especially if done with more than one day of menstrual delay.

What is the value of hCG in the blood test that indicates a pregnancy?

In most laboratories hCG is considered negative when its value is less than 5 mIU / ml.

Values ​​between 5 and 25 mIU / ml are considered indeterminate, which may mean a false positive or a very recent pregnancy. In these cases the test should be repeated after 4 or 5 days to be sure. If it is even pregnancy values ​​will have tripled or quadrupled in this short interval.

HCG values ​​above 25 mIU / ml are positive and indicate ongoing pregnancy.

Can I know how many weeks pregnant I am for the value of hCG?

No. The values ​​vary greatly from woman to woman, and it is not possible to establish a linear relationship between pregnancy time and hCG value. To estimate pregnancy time, we used the date of the last menstrual period and fetal ultrasonography.

Can ultrasonography detect a pregnancy with how many weeks?

Transvaginal ultrasonography is able to detect the embryo from the 4th or 5th week of pregnancy, which means that with one or two weeks of menstrual delay it may already be possible to identify an initial gestation in progress.

I was recently menstruated, but I still think I’m pregnant. Can I take the test?

You can. If you have really menstruated, there is no chance of being pregnant. However, some women have a small vaginal bleeding at the time of implantation of the embryo in the uterus, which can be mistaken for a weak menstruation. Therefore, if the doubt persists, it does not hurt to take the test.

I had an unprotected relationship, but I took the morning-after pill, do I need to take the pregnancy test?

Most women menstruate around 1 week after using the morning after pill . However, in some cases, menstruation may take longer. It is recommended to take the pregnancy test if the menstruation has not appeared after 3 weeks of use of the pill.
