Should I test

Today is day one of my missed period, me and my bf has a miscarriage jan 12 and haven’t really been trying but have been trying at the same time cause we’re scared. I ovulated on the 25 of March and that’s when we had sex we also had it a few days before. And now my period didn’t come I have taken 2 tests a few days ago and nothing popped up just negative. So I’m not sure what to do here
