Does anyone NOT take prenatals or any other type of vitamin once they hit the 2nd trimester ?

The prenatals were making me very sick. So my doctor switched me to: 2 Flinstones, plus a Folic plus a DHA supplement. We think these are what have been causing extreme hives all over my body. So now that I’m in my 2nd trimester, my doc said I can try not taking any vitamins (since I’m not throwing up and I’m able to eat a good diet and not nausea, not avoiding food, etc). Anyone else experience this?
