If Met is working for you (weight loss wise, and hopefully TTC wise as well), are you going to ask your Dr about going back on it after pregnancy?
We're not going to be trying again, so I don't have an IF reason behind taking it, but it really did help me in losing weight, and given that I had GD with DD's pgcy, I would like to avoid getting type 2 diabetes in the future, and know that part of that is going to be getting to a healthy weight.
I don't really know how to even go about broaching this subject with my dr though. I don't want to seem like I'm using Met as a diet pill or anything (though, really, who would willingly take the stuff?!), but I truly feel it helped level out my hormones enough to allow my body to burn fat and lose weight.
