Progesterone suppository side effects?

Stachia 🌙 • Fur mama 🐾 12.4.19 👼🏼

This is my 4th medicated cycle and my first with a specialist. I was on Letrozole and Clomid at the same time and have been on estrogen since my trigger and now added the progesterone suppository until I test next week. My question is are there any side effects I should be prepared for??
