question: i have been trying for a baby and had sex around ovulation. i come on my period a day late but my period is not the same as usual. it was really heavy for 24 hours and then stopped for 12 hours then there is only a small amount of blood there now. also i have really bad stomach cramps and stabbing pains at the top part of my stomach just before where my rib cage meets. i normally have a 7 day cycle and i never have any types of pains normally. could this be something to worry about?
