Metformin Success Stories??

Kristen • Been with my husband for 4 years. Married since March 2015. Praying our little miracle is on its way as we TTC #1. ❤️
My doctor has put me on Metformin. She figures I have PCOS.. (Cysts were found on my ovaries) 
Anyways. It's making me feel really bad nausea and get headaches. Is that normal ? And has anyone gotten pregnant on it ?
I'm trying really hard to bear the nausea but it sucks 😔
Hoping this metformin works.. Success stories ?
