After fertilization we arrive at week 4 of pregnancy, which is considered second development: is when the embryo implants itself in the wall of the uterus (the place where she will grow and prepare to go outside on the day of delivery). The correspondence is with days 21 to 28 of the menstrual cycle; but menstruation has been stopped by the hormone human chorionic gonadotropin (HGC) which is what pregnancy tests detect. Therefore the absence of menstruation - especially if pregnancy is sought - is the first sign to observe; And remember that if your suspicions are confirmed you should (if you have not already done so) start taking folic acid supplementation, as indicated here (400 mg daily).
Between this week and the next is when we usually ask for a pregnancy test at the pharmacy or Family Planning Center: if the rules are irregular, Perhaps it is convenient to wait a few days, although I know that in this circumstance patience is conspicuous by its absence. If you buy the pregnancy determination kit, read the instructions carefully, and always perform the test with the first urine in the morning; HGC remains continuously in the urine, but this is when the concentrations are highest, and performing the test at noon could give a confusing result. The lack of menstrual bleeding is the first warning, and if it is a wanted pregnancy, it is inevitable to feel a twinge of illusion, but there are more signs, and they are unmistakable (for those who have already had one or more pregnancies).
Nausea or dizziness may appear, and you are sure to be tired; it is also common to feel tension in the breasts. Although the sensations are similar to those we have with premenstrual syndrome (with the exception of the sadness that sometimes accompanies the latter), it is intuition that alerts some moms; Y the two pink lines that confirm to all of us that the pregnancy has been achieved! But let's not go so fast and go back to that implantation.
The embryo looks for a house
After fertilization, the blastocyst (the embryonic phase has yet to begin) descends to the uterus and generates small extensions that embed (or bury) it in the endometrium: implantation has concluded and the being that will develop from this cell division already has a home. At the same time, the formation of the placenta and the amniotic cavity begins.
The size of the small implanted embryo prevents the ultrasound from detecting it, although a vaginal ultrasound could help to see the yolk sac without evidence that new life is pushing hard inside. There is only another week left for you to see it, and I know that even if I tell you that there is no rush, you do have it; It won't do you much good if I tell you that if your baby is already with you, you can just take care of yourself and take care of him, and go to the appointments scheduled by the midwife and the gynecologist. Fortunately, today we have at our disposal a lot of information, and virtual spaces where we can share with other mothers. However, I repeat: relax and enjoy this new stage of your life, contrast data when necessary and let yourself be carried away by instinct and the advice given by health professionals.
Implantation bleeding - nothing to worry about
The embryo is small but its three layers of cells form different tissues: the inner one will become organs; the average in the skeletal, muscular, excretory and cardiovascular systems; the external will become skin, hair, eyes and nervous system. Well, this is very, very briefly; but of course Nature works perfectly, there is no doubt that she knows what she is doing :).
This week what we know as implantation bleeding happens: while your body takes care of avoiding menstruation through a series of signals, and as the help of HGC; the blastocyst causes bleeding that is normally small, by wearing away the tissue that lines the endometrium (very sensitive at the moment, and irrigated with the blood vessels that will nourish the new being). This bleeding is usually darker than menstrual blood, and sometimes it is no more than a couple of drops, so do not panic if it presents these characteristics.
You have just seen a video that can clarify some doubts. There is a long way to go, but do you realize the great quantitative advance that has occurred in a few days? From fertilization between two cells we pass to an organism made up of three layers that begins to nourish itself; but also the placenta, the amniotic sac, and the mucous plug are developed, to avoid infections and protect what will be your baby.
We invite you to continue with us this series about pregnancy. Enjoy it!

Hello my name is YOHANA and I am worried because I cannot get pregnant and I will do my urgent treatments I want to be a mother
Yohana, see your doctor please. Thank you very much for reading and commenting.
Hello I am very worried because I have a delay of 15 days and on July 22, 2017 I went to the laboratory to do the pregnancy test and it came out negative, 3 hours later I had a slight bleeding which has not occurred since on July 22, 2017. What could be happening?
Hi Jessica, wait a few days to take a new pregnancy test, for example you can repeat it on August 31. We do not know what the bleeding may be due to, if it has not been repeated, do not worry.
Hello. My question is the following. I am looking for a baby and on my 21st day of the cycle I was prescribed antibiotics (bactrim forte and another medication) for a very ugly folliculitis infection. My fear is if taking these medications can cause any harm in the event that this month I have managed to get pregnant, even without knowing it, since my period date is for this 26th and my cycles are 30 days. Thanks
Hi Gina, we understand your concern, but you should try to eliminate negative thoughts. These doubts are always better to consult with the doctor, even to trust the doctor who wants to prescribe medications, and tell him that you want to get pregnant, so that he has that information. If you have become pregnant, think that a few days elapse until implantation, in which the risk of what the mother takes is minimized, but it is not advisable to trust that either. Talk about it as soon as possible with the doctor or doctor, and take the pregnancy test if you have a fault.
A greeting.
Hello, I haven't had a period for a year, we didn't take care of ourselves with my boyfriend, today I got a cramp and I started to have pink bleeding. I feel something beating in my lower abdomen. Will i be pregnant?
I had sexual intercourse on the last day of ovulation, and 47 days later I performed a qualitative blood test with a sensitivity of 25mIU / ml giving a negative result ... but the symptoms of pregnancy persist such as granites in the breasts, abdominal distention or a swollen belly , and a white discharge ... is it possible that so many days later the pregnancy has not been detected? Could it be an ectopic pregnancy? Or maybe I am creating a psychological pregnancy? I did an abdominal pelvic ultrasound and my endometrium is thickened.
I had a delay of 15 days and I did a test came out positive and after 5 days after the test I started a slight bleeding only spots and few drops when entering the toilet in an echo I did not look at anything k does this mean
Hello, my name is Marta, I just want to know I had my period on June 19 and only for 3 days then I had relations with my husband on June 24 and on June 29 I started to stain like something pink between brown until today I still want to know why thank you
Hi Marta, implantation bleeding can be pink or brown, but we can't answer the question. If you want to find out, take a pregnancy test, or wait.
All the best
My last period was on June 7, I was late and on July 13 I took a blood pregnancy test and it came back positive, but on the 17th I started to bleed, it was red like blood, not brown or pink as I have read that it is the implantation bleeding, I went to the Dr., she did a transvaginal and she told me it looked like an abortion because she couldn't see anything, the next day I went with another and she did a pelvic echo, but I think both of them were wrong with their diagnoses, already I have read that with 6 weeks you can see nothing but the bag, and in the pelvic you do not see anything. They told me that she may not be pregnant. I'm confused, please help me.
good afternoon
I have a question and I want to be taken out of it, it happens that on April 7 of this year I had relations with my partner without protection, we used intercourse. On April 28 I got a slight spot which I confused with menstruation this hard just 1 day I did not give it great importance. On May 5 and May 6, I had sex with another person without protection, we also used intercourse, if the period did not come any more, I took a pregnancy test in June which came out positive as of today, September 17, 2018 I am 21 weeks 2 days. And the truth is, I'm afraid because I don't know who the baby is, I'm waiting for, please help me clear up this doubt.
Thank you
