Late period or Pregnancy? Too early to know?

Hi guys! So I’ve been in a dilemma. I got my period January 31st which lasted until Feb 5. I had sex Feb 15-17 unprotected, which is around the time I ovulated. I took a test Tuesday and it was negative (although I screwed up the test, please don’t ask how I mess up at hpt, lmao.) I took another test Tuesday night and I got an error message. It’s now Thursday March 7, and still nothing. Should I take another test?
