I believe it is, but I’d be getting really specific advice from a qualified nutritionist.

I agree with cheshirecat13. I hope you have a vegan friendly Gp, otherwise I wouldn’t seek her/his advice, but rather seek the advice from a vegan friendly Nutritionist

Being vegan myself, if you are already vegan. I would personally stay committed to being vegan during pregnancy . One of my friend’s went vegan before me, and had been during her pregnancy and after pregnancy too( whilst breastfeeding). I’d definitely get advice from a professional though, like a dietician and or GP that is vegan friendly( if you have concerns).

I think eating all types of foods keeps you healthy and gives you all the nutrients you and your bub will need

Not 100% sure on this topic, apologies, but extensive research is a must for you to do I believe and asking your regular or any GP of their opinion would be wise as well.
