What happens in the 4th week of pregnancy?
This week is perhaps the most important week of pregnancy. Because the expectant mother is realizes that she is pregnant at this week.
This week, the first cell of the baby (Zigot) occurs. The zygote starts dividing rapidly.
For example, 2 cells, 4 cells, 8 cells and 16 cells and continue to divide. The journey after the division leads the divided zygote (embryo) into the uterus.
When the embryo reaches the inner part of the uterus, it tries to find the perfect place for itself. It settles there earlier this week. Usually the perfect place is the upper part of the uterus posterior wall.
When the settlement occurs you can see a bleeding in the form of spotting, do not panic. This is called implantation bleeding. This bleeding may occur between the 3rd and 7th days. The cause of the bleeding is that the embryo crashes into the capillaries during the placement.
In normal cases, your menstrual bleeding is at the 4th week. If you want to get pregnant, you hope not to see bleeding this week. You may say “I wonder if I’m pregnant?”. There are ways to resolve your doubts! A pregnancy can be diagnosed at 4 weeks by looking at certain hormones in the blood. However, this test is performed by taking blood.
