No period

So my last period ran from Nov. 24-28. I haven’t had any bleeding or spotting since then. I’ve taken 3 pregnancy test: one in December two weeks after missing my period then, one right before my period was suppose to come this month, and one a few days ago. (All negative) I am now wondering what I should do...? Should I go see a doctor or wait a few more days/weeks and test again?

The glow app tells me I’m 33 days late bc it’s basing off my first missed period date (22nd of december). My best friend is pregnant and told me it took 6 weeks for her to get a positive pregnancy test. Should I wait until 6 weeks from the glow app and test again?
