During the second week of pregnancy, a woman may realize she is pregnant. This is often around the time a missed menstrual period might prompt her to take a pregnancy test.
While not explicitly a part of pregnancy itself, it’s also worth noting that the second week is commonly associated with the luteal phase of the menstrual cycle, during which ovulation occurs and the body prepares for a potential pregnancy. However, conception (formation of the zygote) typically occurs in the first week when the sperm fertilizes the egg.
