I had unprotected sex november 29 right after my girl friend finished her period. When we were having sex i pulled out the first sign of a sensation i was going to *** . When i pulled out the first time i moved away from her and about 25 seconds later i began to to pre *** on the floor i went in to the rest room and cleaned my self off then i went back and had sex with her and as followed i pulled out walked away and i came on the floor.the days after i began to get paranoid so i asked her to take a pregnancy test she took the test on October 10 and it came out negative . But i still in my mind think shes still think she can get pregnant or is going too. Do i have something to worry about ? or am i over thinking too much?could she be pregnant? iknow the test said negative but for some reason im still paranoid.
