Cultural difference


My roommate is Egyptian. Sweetest woman with the best intentions, but I think there is a major difference with being pregnant here, vs in Egypt. She has insisted I stop taking my prenatal until 2nd trimester and only take folic acid and says the vitamins will harm and deform my baby. She asked me today if I was still taking them and I said yes per doctors orders and she started yelling at me that it’s going to overgrow and deform my babies skin. She then starts talking about how once I’m 2nd trimester my pregnancy hormone stops and that’s why you no longer feel sick, and you’d even get a negative pregnancy test if you are 2nd or 3rd trimester. Is there any truth to any of this or should I just ignore what she’s saying? She says she has medical background from Egypt. It’s stressing me out. Lol
