My boyfriend and I had unprotected sex on the days I'm supposed to ovulate. We had sex on the 25th of October around 1am. My ovulation days where the 24th to the 29th. I did end up taking next choice one dose on the 31st at 11pm. That would be a little over 4 days. Could I possibly be pregnant? It's been a week I still haven't recieved withdraw bleeding either from the pill. I did experience sore breast.
