Pregnant??

Ok so, my period came on the 8th of this month..
Me and my boyfriend had unprotected sex like the day before my period came, and like two days after, and again this week.. On sunday I felt really sick when I was making my bed, and had to run to the...

bathroom and throw up.. I've been extremely emotional, I cry for almost no reason lately. I have some weird food cravings and my boobs are starting to hurt somewhat. and I have been getting really tired a lot, and taking naps sometimes threw out the day, and also have really bad lower back pain. My boyfriend said that his ex, had the same symptoms when she first found out she was pregnant. I looked up online and a few sites say that it is possible for me to experience symptoms like this as early as a week, but I just wanted personal opinions from people who have been pregnant before, as to if you think I am or not. Please no rude stupid answers about, learning about sex before I have it and all that. Im old enough to make my own mistakes, and I hear it enough from friends and family, the last thing I need is to hear it from a stranger. Im just asking for some advice on this situation, not your opinion on if what im doing is right or wrong... Thanks =)

Well, those definitely are symptoms of pregnancy, but they are also flu and PMS symptoms.

If you got your period the day after you had sex, then it's less likely that you are pregnant, but it's not impossible. Your next period should be due soon - wait to see if you get it and take a test if it's late.
