Hi. Last wednesday I ejaculated before my girlfriend came over and the sperm got on my hand and on my penis. About thirty minutes later she came over and I fingered her(not sure which hand) and we had unprotected sex for about 10 seconds (I didnt cum) or less, it was like one or two thrusts. She has been feeling sick since saturday and her head feels warm today. her last period ended september 5. please help.
