Vitamins/medication

Dana • My husband and I have been TTC for 4 years. Two with a specialist.
Just curious as to what vitamins/ meds are everyone is taking while TTC. 
I'm taking letrozole 5mg for 5 days (days 3-7), estradiol for 7 days (days 12-18) and will need to take progesterone vaginally for three days after <a href="https://glowing.com/glow-fertility-program">IUI</a>. 
I'm also taking prenatals, B6 and B12 vitamins.
