So about 2 weeks ago (on July 13) I was bleeding a bit but had finished my period a week earlier. I checked my birth control pack and realized I was a day off on my birth control. I was pretty sure I took a pill the night before (July 12) albeit a few hours late, so I really have no clue when I missed the pill. I doubled up that day to get back on track and continued as normal. My fiancé and I had sex on July 6 and did not use a condom. Since I don't know when I missed the pill, I don't know if it was before or after having sex (hoping after) and we haven't done it since because I'm nervous. However, ever since July 13 (when I doubled up and potentially took my pill the night before meaning taking 3 pills in less than 24 hours), I've been spotting (brown and light pink) and having serious stomach discomfort. I've been on the pill for about 8 years and although I do tend to experience spotting between periods, the cramps and stomach pain makes me anxious. I am supposed to get my period tomorrow or Friday. What are the chances of pregnancy if I missed that pill before sex?
