Most people do not have any symptoms after the follicle is expelled. A few people experience a slight cramping pain in the lower abdomen at this time, and some people may experience post-ovulatory bleeding. If your period is very regular, once every 28 days, you will ovulate on the 14th day of your period, and there will be no difference of two days before and after. The normal time to have a period after ovulation is the 14th day after ovulation. If you do not have a period for more than 16 days, the possibility of pregnancy is very high. If the menstruation occurs on less than 12 days, it means that the ovaries are not functioning well. It is possible that the progesterone secreted by the corpus luteum is reduced, so the corpus luteum is not able to maintain its normal function and will come early, so if this phenomenon occurs, menstrual regulation and ovulation promotion treatment can be carried out.
