It is possible to have a small amount of vaginal bleeding or abdominal distension a week after the day of ovulation. 1. A small amount of vaginal bleeding: If a woman has intercourse during ovulation and does not use contraception, then it is possible to become pregnant. When a woman becomes pregnant, the fertilized egg will settle in the uterine lining about one week after the intercourse, and during the process of the fertilized egg’s settling, it may cause the local uterine lining to rupture and bleed, resulting in a small amount of vaginal bleeding. 2. Abdominal distension: After ovulation, if the fertilized egg is deposited in the endometrium, it may cause abdominal distension in the process. If you have any special discomfort after ovulation, you should go to the hospital as soon as possible to find out the cause and exclude the possibility of pregnancy.
