Hello, my husband and I had unprotected sex on November 26th. My period was due November 28th. It didn't happen. Then on November 30th we had unprotected sex again. On December 2nd I started bleeding but it wasn't like my normal period. It was very light and had a pinkish tint. It only lasted two days. I have taken pregnancy tests but they have all come back negative. I have some symptoms but I believe they could be in my head. Anyway, they are, Nausea, Cravings, Bloating, Mood Swings, and Headaches. I don't want to go to the doctor if I don't have too.
