Metformin effects on progesterone

Hello!

I started spotting before and after my periods about 6 months ago. My cycles have been irregular my entire life. I've been off birth control since November 2024.

I came across something on here that made me think my progesterone is possibly wonky. I started ttc last month and was unsuccessful. I am seeing a virtual women's health doctor every other month until my appointment with a local obgyn for preconception in July.

Anyway,

Has anyone had luck with metformin correcting a hormone issue like this? I've been on 1000mg since May 2025 and the new doctor is having me bump up to 2000. Is there anything else I can do in a more natural way until I can meet with her in May to discuss it?

Google says diet and exercise. Has diet helped anyone?

Any insight at all is definitely helpful! ☺️
