My period is always always always on time and its a few days late this month. And no sign of it either. Usually get awful back pains and stomach cramps up to a week beforehand . Me and my boyfriend had a few nights out around that time and stupidly (please no lectures) didnt use any protection. We've jus split up so havent really got anyone to turn to. Dont even know what I want from this really.. jus needed to write it down..
