I have been getting g period like cramps & running to the bathroom aloot... I have tested for pregnancy 3 times & it comes out negative.. . could I be pregnant

You could be pregnant, but you are testing too early. You are now playing the waiting game and have to wait to see if your next period comes as expected. If not, test using first morning urine following the directions carefully.

Yes, (if you really ovulated at that time, of course unless you are testing for it, you would not know)

I will also assume sex was unprotected. So it would appear you are trying to get pregnant, having sex right at the est time of ovulation.

You will need to wait and see if you miss your period, and if you do, wait at least one week, (two is better) and try a pregnancy test.
