I can't remember exactly when my last period was but it was probably around the 27th of june. I always get severe cramps and they always start about a week before i actually get my period but ive been getting severe cramps for at least 2 weeks now with no sign of period. Me and my boyfriend do not use contraception but have only had sex a couple times since my last cycle and we use the 'pull-out' method. Could I be pregnant? I wanted to wait before I actually take a precnancy test but im getting pretty worried.
