Hey ladies, my husband and i have tried ivf three times. we've only made it to retrevial once, due to poor response. I'm 26 and was diagnosed with pcos. my peroid have always been regular. I am over weight (242 lbs) and started metformin in october. since starting metformin i've lost a little over 20 lbs. do you think if i lost more weight i would respond better to the meds. I know some hormones are stored in fat expecially belly fat. Just wondering what you ladies think.
