Too much folate ?

Ma

Hi ladies . So up until right now I’ve been taking probably around 2000 mcg folate c 600 from my

Prenatal, 600 from a stand alone folate supplement , and then there’s about 800 in my b12 supplement .

I just read somewhere that there is a link , but not proven or peer reviewed research, that an excess of folic acid can increase the risk of autism … what should I do now , I’m 10 weeks tomorrow . Is it okay to suddenly reduce my dose back to the regular 600 that is in my prenatal? Do any of you have any experience with this ? I’m also going to call my doctor on Monday .
