My fiancee has had a weird in-between period thing for about a week, and this just about a week ago. She had very slight bleeding for about a week with red to dark red to pink and sometimes brown. She had constant cramps for nine days during this as well. A week later her period is supposed to come on the 26th.
She is fine and on birth control and tells me she feels good but her upper back has been hurting for the past four days and she is starting to get cramps on and off again. We had sex two days before her last period and I have a strong feeling that it is just the birth control doing this. I used a condom and made sure there were no holes. Before I finished I pulled out but the condom slipped off and it got stuck inside of her and she said nothing was coming out of her after this happened. Is birth control the cause of all of this?
