Is it too early for symptoms?

Soo.. I am silly and didn’t realize I was one day from ovulating and my husband and I had sex.. and I don’t know if it’s in my head but I already feel like I’m pregnant. We had sex on Wednesday April 1st and Thursday 2nd and ovulated on the 4th. Starting Sunday night I had mild cramping and was nauseated, Tuesday I am completely drained and nauseous on and off. I want to take a pregnancy test ASAP! Any recommendations on when I can take one and which test should I get?! Thanks girls 💕
