Is this normal ?

So i had sex recently but i got my period last Thursday but weirdly enough i haven’t been cramping as bad as usual and i haven’t been as heavy as usual . It’s around the time i should have my period so thats not out the norm. But its weird how it isn’t usually the periods i usually get. Could i be bleeding cause I’m pregnant ? Btw he pulled out but you know theres always a possibility . Anyways is this normal? Could i just be spotting/bleeding cause I’m pregnant. I haven’t noticed any symptoms btw
