Hello. I started taking birth control pills in Septemeber for two months, but I stopped for a month, I know that was not the best but I did it because I was feeling terrible and was under antibiotics which were making me feel depressed. I started again the pill three weeks ago. I got my period on Sunday afternoon (very light spotting, strong blood at night) so I started the pill next day at 10 am because I wanted to start in the morning. I haven't missed a pill. However, I started having strong breast pain since two weeks ago and on friday/saturday I had light brown vaginal mucus. I'm very scared of being pregnant. I've taken a pregnancy test on friday and today, and both are negative, but I don't know if it's too soon. Is there a chance that I'm pregnant?
