I have been taking Birth Control for a year now, I havent missed a pill and always took the pills within 3 hours of each other. Though, this past month me and my boyfriend just kinda fooled around without protection but he didnt actually finish. We fooled around on a Saturday, 2 days later I fell asleep and took the pill about 8 hours late (this was my first missed pill) , the day after I started having some light pink but mostly brown spotting and it lasted for about 4 days. Well, now I am past my placebo week and haven't had a period. Could taking that pill late cause me to miss a period? Im worried for pregnancy.
