First off.. Im hoping .B.J. Easley isnt the guy that u slept with.
Secondly, if you dont know anything about pregnancy, dont have sex. You wouldnt attempt brain surgery with a 6th grade education, would you?
Third, no. Its only been a week. It takes about 4-5 weeks for morning sickness to kick in.
Lastly, what the hell are u doing having sex at school??
