Choline - WHAT SHOULD I DO

I have been seeing how choline is VERY important for the development of the babys brain. But the problem is that I can barely eat eggs, I try my best but i know its not enough. I get nauseous from them. I try eating them but cant eat more than one egg some days. I’m in my 7th week and it’s really hard with the nausea. Can I ask my doctor about any choline supplements?
