I am 11 days late for my period usually I have a very regular cycle. Took 2 pregnant. Test on the 8th day and the 10th day and both were negative. I was fooloing around with my BF I know for sure he did not penetrate me we were rubbing our genital against each other and he ejaculated at the top of my vagina could I be pregnant

Yes you can get pregnant this way. My advice eould be to got to the dr. And if you don't want a baby get on birthcontrol.
