I went off my birth control for a month because I had forgotten to reorder it. I went back on and the following month I had a very heavy period. A week to week and a half before my next period I was spotting (a brown color) and I was sexually active. Once my period started, it was very light and did not last long. I was sexually active a couple times right before I was supposed to start. I have not had any spotting since I stopped. Could I be pregnant? or is this normal after being off the pill for a month?
