I am on the pill, but I haven't been very good about taking it when I'm supposed to. I got EWCM and then about 3-5 days later had unprotected sex. I missed 1 pill that night, but continued my normal routine the following day. 3 days later I started bleeding, so I stopped my birth control for about 5 days and then started taking my pills again. The bleeding stopped within hours of taking one pill. I have been taking it at normal time ever since...does the bleeding mean that I am not pregnant, or is there a chance that I am? If so, what are the chances?
