Folate

I’ve heard that folate is super important in the first part of pregnancy, but if they don’t transfer babies/blasts until they’re 5 days old, then aren’t they missing out on folate in those first 5 days? I want to give my baby the best chance possible at having a healthy life and functioning brain. I’m taking 1000 mg folate right now and still waiting for my retrieval. Any tips?

*1000mcg not mg lol my bad!
