I had sex with my boyfriend a day before my birthday (jan 10th) and we had sex for 7 hours, eventually something happened with the condom and then we had unprotected sex the rest of the night, 2 or 3 days later had spotting....i bled 4 days after (jan 14th-19th) and had symptoms that of an early pregnancy, i took a pregnancy test on the 28th of January and got a negative, then all feelings started to fade away - my period was suppose to be here yesterday & didn't come yet....so do you think i'm not pregnant? or is there still a possibility? i don't know what to think or what to really do....according to calculations, a test should've read positive if i was pregnant by now & i got a negative...so should i just suspect that i'm not...i'm in a grey area of thinking i am but for the most part i believe i'm not...
