hi, im 19 and and am currently 6 days late for my period, i am not always regular but have been for a couple of months before this month. i have had sex with my boyfriend this month but used a condom each time and used it correctly, almost 100% that it didnt break (as it has done before and we knew so i took the morning after) but now that i'm 6 days late im terrified that i could be pregnant. i have no other signs of pregnancy apart from missed period, and i keep getting the same sort of feelings i get when im due on my period so i was wondering if you could give me any other explanation. should i be worrying? i'm too scared to take a test in fear of it being positive. please help.
