Just 1~15 days of pregnancy, most women don’t feel anything, a very small number of people will have a small amount of bleeding when the fertilized egg beds down, and some will not have menstrual periods until 15 days.
At 1~15 days of pregnancy, the sperm and egg have just combined to form a fertilized egg, which is still in a cellular state, and it reaches the uterine cavity in about a week or so to bed in the uterus. At this time, most women do not have any symptoms, and a very small number of them may have a very small amount of vaginal bleeding at the time of bedding, which will be cleared up in a day or two.
At 15 days of pregnancy, estrogen and progesterone levels increase in a woman’s body, inhibiting the shedding of the uterine lining, so there is no period to come.
Most women have a period about 14 days after ovulation, so women who don’t have a period should be on high alert for a possible pregnancy.
