Could I be pregnant??

I've been seeing this guy for a while now, and I haven't been using protection like I should 😔. We had intercourse every chance we had in the month of May and when my period came I was unusually light. And it didn't last my usual 7 days it was only 5!! I'm usually very heavy. I've recently have more of a appetite and I'm sleeping more as well. I'm not due for my next period until the end of this month/beginning of next. I've had cravings and inversions to foods as well as nausea here and there. Help!!! Am I just thinking about it to much or could I be pregnant?Â
