I started taking vitamins like Women's One a day, a b comlex and a protien shake meal replacement (Isopure). Within a month of
stabalizing, I became pregnant. Mind you I have a history of
PECOS, Diabetes, and generally questionable health. I say all of this to say, I believe odds increase the healthier are and more balanced with vitamins. I would engage your ob immediately pre pregnancy to walk through family history, medical challenges, expectations, and risk.
