Should I test?

So I started taking birth control this month so my periods would come back, since every time I have a miscarriage they don’t start back, and my doctor also put me on Metformin to help with my insulin resistance (which caused the miscarriage). So my period was supposed to start today and it hasn’t and I show none of my typical signs or symptoms. And I always start my period on birth control, it never fails. I’m just slightly concerned. Should I take a test or just wait it out?
