Hello, I had unprotected sex after missing three pills in my third week of birth control. I had missed Sunday through Tuesday but took two pills on Wednesday and same with Thursday until I was back on schedule. I had the unprotected sex early early Friday morning and again later that morning. I took emergency contraception on Saturday morning but didn't get my period as expected. This all happened the week of November 9-15 and now it's the 30th and still have not gotten my period. I had some spotting earlier last week but my breasts seem to have gotten bigger and they are sore and I had a horrible back pain last night. Is this just the hormones messing with my body and making me delayed or light or am I pregnant? Please let me know your thoughts!
