How effective is Metformin and Clomid when TTC

Aubree • 26. Wife. TTC #1 2+ years stage 1 endometriosis trying for our rainbow baby
We have been trying for 2 years. 
We have to switch to a different doctor, due to the Dr. dragging his feet in a metaphorical sense... 
Anyone know how successful thoughs are together. my ovulation is normal but not great. Dr.Robbins our new doctor told us my Ovulation results was 13.10 and she wanted it 15.00
Does anyone have success stories or unsuccessful stories?
