New medication advice needed please

Jess • Been with the love of my love for almost 8 years, married 17/08/19 baby boy 💙 👶 05/10/2019 baby boy 💙👶 April 2022 baby girl 🩷🧒 March 2024

I’ve been taking provera & clomid but not ovulating enough, my doc has now given me metformin, does anyone have any advice regarding metformin or any side effects they had?
