polycystic ovary syndrome
"I am 26 and have PCOS. I use this medication when trying to conceive.  I have been TTC for 12 months and nothing was happening so my doctor prescribed me Metformin 500mg in the morning and 500mg at night.  I only had to take the medication for 2 months before I was pregnant. The medication does give me diarrhea at the beginning of starting it but I suffer from chronic constipation so I sort of don't mind that side effect in a weird way.  I do notice I am losing a little bit of weight as I take this medication as well."
