HELPPPPP!!!!!!!

My boyfriend and I had Unprotected sex Sunday, Monday, and Thursday. He then proceeded to tell me he ejaculated in me over two times. My period is set to come today, my period symptoms I usually have have gone away, but I have a small amount of cramping. Can I still get pregnant from this if I had sex only a couple of days before af?

Or if it does come is there a chance my next period won't?
