Supplements? Please share!

Hello all I have recently been doing research on supplements that boost fertility - I am currently taking 
Daily prenatal with DHA
1000 folic acid
5000 vitamin D (low blood count)
From my research i have seen other names like B6, vitamin C, maca etc. 
My main interest is increasing progesterone naturally, and preventing miscarriage. 
Please share what you take and if you've gotten a BFP with that.
