The prenatal vitamins made me feel horrible too, my Dr said takkng two Flinstone kids vitamins a day is fine also.. and theyre yummy so I switched to them.
What brand are you taking? I tried elevit first because they are supposedly the best, was taking for about a week and they made my symptoms ten times worse it felt like! So I stopped them and bought a cheaper brand, Cenovis pregnancy and breastfeeding, it's $15 for a bottle of 50, and it's only one a day. I've been taking them for about three weeks now and if anything they have made my symptoms 2000 times better. I still get a bit of nausea but I can still get up and go about my day, unlike spending my days in bed and with my head in the toilet bowl when taking elevit. Everyone is different though :) also, I work with the daughter of a midwife and she told me to try taking a vitamin B supplement aswell as my prenatal vitamin, twice a day. It really helps with energy and nausea :) wishing you all the best!
The prenatels they prescirbed me made me sick so i switched to a store gummy brand and since i switched they have been amazing
