Pregnancy possibility 🤔

So me and my mans had nonstop unprotected sex for about 3 weeks straight and it says my period is in 7 days, I have some symptoms but I’m not sure if it’s period symptoms or pregnancy symptoms because I read that their similar 🤷🏻‍♀️ I just need ladies’ opinion, do I have a high chance of being pregnant?

Also, should I test now or wait for my period?
