Im having 2 periods a month and my doctor said im not ovulating what does that mean period around the 4th and then having it 2 weeks later?

Ovulation Bleeding: Ovulation spotting is a result of a woman’s changing hormones during ovulation. As your cycle progresses, the growing follicle produces more estrogen. This increase in estrogen triggers a surge in lh, another hormone involved in ovulation. When lh surges, it signals the mature egg to be released and there is a drop in estrogen levels that results in breakdown of your lining and a small period.
