Hello, so I had a missed period for roughly 2-3 months I got my period Wednesday April 9th and now I'm just spotting. But I last had sex March 10th . The 17th of March I took a pregnancy test I had no signs of pregnancy and the test turned up negative. I do take birth control but I lost track of the days and messed up my pills I'm now on track so is it possible I could be pregnant?
