Am a 21 year old virgin. My boyfriend and I Took a shower together and he came but he was not close to me at all. Then he cleans himself and we went to bed later the same night were making out I was naked on top of him but he didn't penetrate me
I was also on the last day of my period right after making out on top of him I started feeling a lil cramps as if I had my period.
I though I was being paranoid the next day I was bleeding just a lil for what I think is just what was left from my period
Is there any way I can get pregnant with his precum if he ejaculated before
it's been two days and my cramps went away. But now it's back.

Please help

thank you.
