Just started metformin again!

Hi ladies just started taking metformin again. I took it about 5-6 months last year I didn't really see any weight loss or was I just not eating the right food? 
Do you guys eat in portions and try to diet while taking the metformin? 
​I'm TTC butttt it's been like over a yr and half that I've been trying and no luck. At first we were TTC naturally.. then was diagnosed with PCOS.. then took metformin..stopped it.. Tried again naturally.. No luck. & and now I'm back to the meds. 
​Let me know your experiences, symptoms, stories, anything!!
