I've just received a phone call from my doctor informing me I need to be put on 5mg of folic acid instead of the 400 I've been taking for the past 2 weeks, I'm 11 weeks and 4 days so now I'm panicking I've not had enough for the recommended 12 weeks, he's giving me 84 tablets so I guess I'm taking them until further into my pregnancy? I'm worried now I've not done enough as I've got history of neurological disorders in my family. Anyone had anything similar?
