I'm on my first pack of Seasonale and I missed a pill on the 22nd of March. I took it at about noon on the 23rd and then continued my normal schedule of taking it at 10:30 p.m. before bed. I noticed dark brown spotting after that. I had unprotected sex on the 5th of April and the bleeding seemed to get heavier after that. It is now the fifteenth and I am still experiencing the breakthrough bleeding. I am worried that I might be pregnant or something else is going on since I have been bleeding this long. Any advice?
