im having some heavy cramping in my left side lower abdomen. it feels like my regular menstrual cramps. but, i aready had my period this month on the 1st. (could it be ovulation??) me and my boyfriend had a pregnancy scare, so i took a plan b about 2 days ago.. could it be from that? i know pregnancy cramps are similar to menstrual cramps, im just really stressing over this. i need some honest answers right now, im only 16 and really need advice. where are pregnancy cramps usually located? like i stated, im only having it in one area.
