Hi, I recently had problems with my cycle I started to bleed 2 weeks before my per. And my doc switched off the patch to the pill. Now two months later I had light spotting for 2 days 2 weeks before my per. Again I asked my doc and she said it is the hormone levels. Well I have never been abnormal ever in my life and this is driving me crazy I took 2 p tests and 1 blood test both negative. What else could this be?
