i have been having unprotected sex with my boyfriend for the past few months but he pulls out before he ejaculates which i know doesnt you can still get pregnant from. i'd been having periods regularily every three weeks which lasted about 4 or 5 days a time but on the 27th august which was a week late already and i then only had a 1 and half day period is this normal or could i be pregnant? i fealt quite sick this morning but this may not mean anything.
