Ladies. Help please.

My last AF was 11/1 and lasted until 11/4. Then 11/20 boyfriend and I had sex. I was put on metformin to try and get me to regulate and ovulate since we were TTC. I'm now 11 days late, but my periods are irregular. Should I test? Should I wait? I'm just nervous! Anything helps!
