So on the 5th of this month I started to notice thick dark brown discharge and sometimes stringy. When I'd wipe it would be light brown and watery sometimes. It's still going on today. My last period was May 17-20 and next one wasn't suppose to be until 2 weeks from the 5th. If it helps, I started birth control on April 24. This past week I have been feeling extra tired, cramps and stomach ache/cramps, bad acne, and diarrhea. My boyfriend and I are sexually active (we use condoms along with the pill) and last time we had sex was May 24. I've overly freaked myself out by researching and convincing myself I could be pregnant. What's up?
