Last month I experienced a chemical pregnancy, according to my OBGYN my next period may come late.

My partner and I had sex the day after I ovulated at 3AM, which also confuses me on which day I should’ve log it as. According to this app my period should come in 4 days however I have no period symptoms but I also don’t have pregnancy symptoms. Should I take a pregnancy test or wait?

Ps. I’m also scared to test early due to my chemical pregnancy experience but I’m going crazy thinking there’s a chance.
