How does menstrual cycle calculate oviposit period abnormally

For women with normal menstrual cycles, ovulation occurs about 14 days before the next menstrual cycle. The first 5 days and the last 5 days are ovulation time, while for women with abnormal menstrual cycles, ovulation time is not easy to calculate. Ovulation monitoring can be performed to measure follicles to see if ovulation has occurred. When the dominant follicles disappear, there is a small amount of fluid in the pelvis, and the woman will feel a feeling of lower abdominal distension or anal distension. Some women also show a small amount of vaginal bleeding, which is considered ovulation.
