What vitamins do you take ttc?

Ashleigh • Married to my best friend. We have a 6 year old son, 1 miscarriage and currently ttc our rainbow baby 🌈👶🏻
First of all, I take Metformin because I have PCOS
I then take a prenatal, for obvious reasons. 
Vitamin D because it helps with egg development and also boosts progesterone and estrogen levels. 
Fish Oil because it helps regulate reproductive hormones and increases blood flow to the uterus which helps with uterine lining development. 
What do you ladies take? Is there anything I'm missing? Is there something else I should be taking?
