SOME ONE PLEASE HELP ME

Alannah
Ok, so I finished my period yesterday but I have been having lots of nauseas after eating an hour ago. I had unprotected sex 4 days after my period (he didn't cum inside me) on last month's period. This month's period came 2 days early which I think is good but this nauseas is making me nervous. Am I overthinking it or should I get tested?
