My boyfriend and I had unprotected sex last month a couple of times.it was my first time to have sex.my boobs are really sore and have grown but I have also grown more of an appetite.im constipated also.I was five days late and started to cramp and thought I started but when I looked I had brown stuff instead of blood.later that day some blood had come out but today I'm not bleeding at all.I usually have an heavy flow.today we went to eat sushi and I couldn't eat much and got very neauseous.but I didn't throw up.am I pregnant or is this just a really abnormal period?

You had unprotected sex.. Yep you could be pregnant. Could be anything. If your concerned about any changes in your period or health best seek medical advice in person to a medical doctor.

unprotected sex= pregnant, not everyone is sick when they are pregnant, go to a doctor or buy a pregnancy test that will give you a definite answer
