I was wondering if you could answer a question I had. My boyfriend and I have been sexually active but safe. We use a condom everytime, but the last week in november or first week in december, the condom broke and i took a plan b the next morning. However, I started feeling sick, and my breasts started getting bigger. My boyfriend and I were not smart, and proceeded to have unprotected sex 3 times on the 12th, 13th,and 14th during which he ejaculated inside me everytime. Now this last satday the 18th i had a small amount of brown discharge that stopped after that day. I have small cramping, like i would have with a period, but no lower back pain. I am extremely exhausted, and throw up in my mouth after every time I eat. I feel tighter across my stomach, and my nipples are extremely sore and the glands around them are raised, as well as I have been having to use the bathroom more. I have taken several hpts but they are all negative. I was wondering if I could be pregnant, and if I am, does my having taken plan b risk the baby having defects? Also, my period is a day and a half late. Thanks!!
