I agree with Special Mom. Take the pregnancy test. Then you'll know for sure.
There is always a risk of pregnancy when you have unprotected sex! I highly recommend always using birth control as well as using protection against std's!!
Okay, so-------- yeah. Always a possibility. At this point you would be able to test to see if you are. Any drug store, grocery, etc. has over the counter tests----------- cheap and accurate. Go get yourself one and find out!!
good luck
