i saw sperm on the outside of my vulva near the opening, he got scared that it would get inside and so he used his mouth to get it off, but didn't give my oral sex yet. he swallowed what was in his mouth and waited a few seconds then gave me oral sex. two weeks past and now i am scared i might be pregnant because i became sick. my symptoms one night were dizzyness, fatigue, and a sore throat. i was also coughing a lot. so am i sick, or am i pregnant?
