Bleeding after sex is this normal ?

So yesterday my boyfriend and I had sex, I thought I was done with my period on the 3rd I did have like old blood before I showered and had sex but after we were done I was bleeding again. And light cramps my period usually last up to 4-5 days yesterday would’ve been the 6th day this morning have a very tiny bit but none when I wiped. Could it be my period
