Sorry if this has already been said, I didn't read all the posts. My cousin and I both have had problems like this. My cousin has had this problem since she was about 14, she had a large cyst on her ovary. I had the problem as well, I had a small cyst, I ended up going on the depo shot which really helped, I was on the pill for several years due to heavy cycles. Let us know what happens in the future! Has she ever had a gyno appointment? If not I would really recommend one.
