Menstrual cycle: Week 4, the implantation

In the fourth week of the menstrual cycle, waiting for the implantation of the fertilized ovum. If you stay away from your period, you can take a pregnancy test. Maybe it also works a little earlier, but it remains to be seen. By the end of week 3 of the menstrual cycle, the fertilized egg has arrived in your womb. In the thick uterine lining the implantation of the fertilized egg start.

Incorporation of the fertilized egg

Approximately 4 to 5 days after ovulation, the embryo, which now consists of about 30 cells, reaches the uterus. The progesterone which ensures the growth of the uterine lining reaches its peak now. This hormone also ensures that the uterine lining remains intact and that your menstruation stops.

The embryo is now also called blastula called. In the womb the blastula floats around while it keeps sharing. Approximately 7 to 10 days after ovulation, the blastula will implant in the uterine lining.

Four of the ten blastulas that reach the womb will never implant!

If the implantation succeeds, the endometrial lining will envelop the blastula. This way he is kept in place so that he can implant himself well. Soon the growing embryo will make contact with the blood supply of the mother.

Am I pregnant?

If the implantation of the fertilized egg is successful then you are pregnant. Your body now also knows that you are pregnant and start making the hCG hormone. The hCG hormone ensures, among other things, that no new egg cells are produced. After all, you are already pregnant. The presence of the pregnancy hormone hCG is thus a way to test if you are pregnant. A few days after implantation, this pregnancy hormone hCG can also be found in your urine.

When does the implantation take place? And can I feel the implantation?

Sometimes a small amount of blood can be released when implanting the fertilized egg. This can be a first sign of pregnancy. It would be a little pink or brown discharge, a few days before you would normally have a period of time. However, most women do not notice the implantation.

Nowadays there are also pregnancy tests available that can give a positive result a few days before the normal period of disability. Still, it is wise to wait until you are actually "on time" before you start testing.
Also after the implantation of the fertilized egg you can still go wrong at such an early stage. That would mean that you test positive, but a few days later again period.
