Metformin question

Georgia • TTC baby #2 ✨️✨️

Hi everyone 👋

I was on normal metformin for 6 months and I found out I was pregnant, unfortunately I had a miscarriage 1 month after. I started back on metformin and it’s been giving me a bad stomach.

I phoned my doctors today and they have put me on slow release metformin. What is the difference? Did it help anyone?

Pros and cons?

Sorry for the questions!
