Okay heres the scoop... Im not sure if I could be pg or not..I think I may be...Last week I was put on an antibiotic..And I just found out yesterday that when ur on an antibiotic it doesnt make the pill as effective... Well over the weekend my bf and I had sex and all that and didnt use a condom but he didnt cum in me..But sunday night it was just the heat of the moment and all and we didnt have a condom...And I sorta think he came in me..The reason I think that is because after we were done hes like "whoops" but I didnt think anything of it...Then I told him that when I was on the antibiotics the pill isnt effective and hes like "wait when did u start those" so I told him and hes like oh.... But im not sure my period isnt suppose to come for at least 2 weeks..Which sucks...But we have had unprotected sex b4 but hes never exactly cum in me... But I just dont know lately ive been having really bad pains in my stomach and the doc thinks I have an infection or something but I think im pg but not sure... Plus ive had headaces I mean major ones....And then also ive been getting sick to wear im wakin up in the middle of the nite puking so what do you guys think the chances are?? Please help asap
