I actual have my period last for 5-6 days. On the 4th December I started my period and my boyfriend and I make love on 6 & 7 that is during period still. I finished my period on th 8th Dec. Since then my menstrual cycle has drastically changed to 24-26 for two months, instead of usual 28 days. Or am I pregnant? can I fall pregnant if make love during my period without protection?
