I got my period on metformin?

Selena • I`m 22 😊 i got married June 11 2015, we have been TTC for 1 year and 6 months. I have PCOS and Diabetes.
I got my period on metformin? So dose that mean my Dr won't put me Clomiphene now? I have (Pcos) and diabetes not that it matters.
And my ovulating CM doesn't look like it should. it's not clear just a funny yellow and stringing 😕 could I have a infection?
