Really need advice

Laura

Girls I really need advice, I had sex with my SO a few weeks ago, a condom was used and everything seemed fine, after that though I did get cystitis but that had passed, we had sex 2 days ago however this time unprotected (I know very very silly) and recently I've been really tired and now I'm feeling nauseous, my period is due in 2 days, am I overthinking or could I be pregnant? I know it's a very extreme thought but I want your advice xxx
