Lately I've been having an issue. A few days ago, I started having a thick, brown, creamy discharge with small white clumps in it. There has also been lower abdominal cramps. The discharge comes out in large amounts. On a side note, I've been taking Sprintec birth control for about 5 months now. Considering I don't have to get up so early anymore, I don't take it around the same time everyday. Please tell me what this could be.
