I had a pretty gloomy 12 week scan followed by harmony test which came back negative but I just realised that I've completely forgotten to take my normal vitamins (folic acid, omega 3, pregnacare and probiotic) since the bad scan. So weeks 12-16 I've somehow managed to completely forget them. It's like some horrible mental block or detachment thing going on.
Anyway.... Is the folic acid just essential in first trimester or are you supposed to take it the whole way through?
I think it is mainly the first trimester and pre pregnancy that it is recommended, but to carry on if you want to.
Don't worry, I kept no Folic Acid down whatsoever for any of my children due to hyperemesis and they are all fine. I hope this one will be too. There is Folic Acid added to bread and cereals which helps.
I'm sure you'll be fine just try & keep & taking them from now on every day. I took Pregnacare from week 5 until the day my daughter was born, as they contain multi vitamins too I was advised to take them until the end.
Many foods are fortified with folic acid in Canada, and it might be the same in the UK. It's possible you've been getting folic acid in your diet even though you haven't been taking it. Even if that's not the case in the UK, I've heard the neural tube defects occur very early in pregnancy (which is why women of childbearing age are advised to take it even if they're not trying to get pregnant), so I wouldn't worry.
