i was with a guy almost a year ago who tried to have sex but i fought him off before he could finish if you know what i mean.i bled alot after that but i didnt think i had really lost my virginity, then i really had sex with a different guy about 2 weeks ago.we had no protection but he pulled out.i know thats not effective, i dont know what i was thinking, but i havent had my period in over a month.it usually comes around the beginning of the month like the first, its the ninth now and still nothing, i cant remember if i even had one in the beginning of last month, but i hadnt had sex before then.could i be pregnant?
