Late Period

Hay everyone! I’m about 3-4 days late on my period but I feel some serious cramps the kind of cramps I know come from my period. My boyfriend the other day fi**ered me and had a tiny bit of blood (he didn’t cut me from the inside) and the next day the same thing happened. So, I’m confused. Is there a possibility I’m pregnant? Also, I have been putting in tampons just in case could that delay it?
