My Body – Pregnancy Week 2Brought to you by
Week two of your pregnancy begins at the end of your last menstrual cycle.
As your period comes to an end and your uterus has shed its old lining, it will start fresh to to prepare to welcome a fertilized egg. Your uterus will form a new lining of blood-rich tissue to house a fertilized egg (or for fraternal twins, two eggs). While your uterus is getting ready to welcome the egg, one of your ovaries will be preparing to release an egg during ovulation.
Some women can actually feel ovulation in the form of one-sided abdominal pain, called mittelschmerz (middle pain). About 20 percent of women experience mittelschmerz – and this pain may occur just before, during, or after ovulation. This pain can be felt on the same side, or it can switch sides from month to month.
Mittelschmerz may be caused by a number of factors. Just prior to ovulation, follicle growth may stretch the surface of the ovary, causing pain. During ovulation, fluid or blood is released from the ruptured egg follicle, which can irritate the abdominal lining. Some women are more sensitive to the hormonal fluctuations that occur during the menstrual cycle and other women may suffer from cysts on their ovaries, which can cause discomfort during ovulation as well.
