Heavy vaginal bleeding or bleeding that occurs before 12 weeks may mean a serious problem, including an ectopic pregnancy or miscarriage. Heavy vaginal bleeding or bleeding that occurs after 12 weeks also may mean a serious problem, such as placenta previa. Ovulation can cause mid-cycle bleeding. Polycystic ovary syndrome (PCOS) is a hormone imbalance that interferes with normal ovulation and can cause abnormal bleeding.
The answer to this question depends on what is considered a period. Menstruation or a period is the bleeding that occurs when the endometrium is shed 12 to 16 days after ovulation. With this definition of a period, you cannot ovulate while on your period. However, some women experience mid-cycle or ovulatory bleeding (bleeding that occurs around ovulation) and may mistake it for a period. This can be seen in some women who have very irregular cycles, maybe coming once every 3 months or 2-3 times in one month, although it can occur in women with regular cycles as well.
