18 weeks with no prenatal vitamins ect

So I just found out I'm pregnant; 18 weeks. I obviously haven't been taking folic acid or anything! Will my baby be okay? Not got a scan for 2 weeks

* I didn't know I was pregnant as I got told in 2016 I was infertile so when my periods stopped I thought it was just because of menopause or something (eventhough im only 23) because I was supposed to be infertile 😂

We're really happy about this pregnancy though 😊 we were just taking about surrogacy or adoption a few weeks ago to start our family!

But anyways... Will my baby be okay even though I've not taken any vitamins ect
