i have been having very heavy cramps for 5 days my period is not due till the 16th am i pregnant, my ovulation was around the 2nd

OK so here it is you might be but it is really tooooo early to find out. I knew I was pregnant days after it happened but the pregnancy wasn't confirmed till weeks later. Give it a few weeks and take a test. Like if you have a 28 day cycle give it until Dec 4 and take a test in the mean time take it easy and just sit tight.

it is normal to have cramps during you pregnancy. but if you dont get you period buy a pregnancy test.
good luck!
