i havnt had my period since febuary. me and my boyfriend had sex for the first time in febuary also but we used protection and he checked after that it hadnt split or anything, and we have done it a couple more times since that but he always checks and so far he says they have all been fine. but i am really worried that i could be pregnant. i have done 2 home pregnancy tests and both have come back negative. i just dont know what to do, im going out of my mind.
i still seem to get the usual pains that i would get when due on my period but each month it never seems to come. although my periods are sometimes irregular it has never been this bad before except for one time when i was late by 2 months (i think).
can anyone help me? please?

thanks, amy.
