Meformin

I am 25 years old and married for 3 years and 4 years in dec to be exact. We want a baby now and the doctor put me on merformin since I have PCOD. Also she gave me 5 days pill to take on the 2nd day of my period to stimulate my ovary. She prescribed me to take metformin twice a day. However because I am a total medicine freak I can't take the metformin as prescribed. I seem to miss days in between also sometimes take 1 pill daily.

Right now I am on my ovulation and I am worried this would end in an disappointment.

Is there anyone on metformi right now? Does it work only if you take it regularly? What should I do? I really want to get pregnant!!
