Hello, I am experiencing bleeding/spotting after sex or orgasm. I have been tested for chlamydia and gonnorhea both of which came back negative. I am on the contraceptive pill rigevidon for over a year and only started experiencing this last month. I always use protection when I am having sex and have a regular partner of two months. I have been tested before I got in a relationship with him and this was negative as well. I am just concerned as to what this would be.
