So my bf and I had unprotected sex on November 1st. I am on the birth control pill and i take them everyday with at most 2 hours after my scheduled time but usually the same time everyday. I have been on them for about a year and half. He did not finish. My boobs have been so sore for about a week and they feel very heavy and I also have been using the bathroom more frequently than normal. Should I be worried that I can be pregnant?
