My menstrual cycle is a normal 28 days. I just had my last cycle on Jan 20 for the usual 4 days. Then just 2 weeks later, i started spotting. A week prior to the spotting, while having imtercourse with my boyfriend, i experienced major cramps and we had to stop. I am now, technically 3 days late for my period. I've t. aken a hpt, could I be pregnant?
