PCOS & Metformin

Taylor
Hey ladies,
 I was wondering if anybody had had any luck with Metformin trying to conceive? I just started 500mg. Due a pill for a week and increase to two next week than 3. Also was told to lose 15 pounds, eat a lot healthier.  Going to start meal planning and hitting the gym, weight lifting and no cardio is what my doctor told me. Anyways who has had good luck with taking Metformin while trying to get pregnant? Thank you!
