Prenatal vitamins making morning sickness worse?


Hi everyone! I was wondering if anyone is having problems with their Prenatal? I take the one a day prenatal with the extra DHA supplement. I am at 6w 1d and the last 4 days my "morning" sickness has been unbearable. Yesterday I couldn't keep anything down, including water or ginger tea. Today I accidentally missed my prenatal but have noticed that while I'm still very nauseous, I can keep fruit, water, and popsicles down. So I was wondering if anyone else has ever dealt with this severe morning sickness or their prenatal making them more sick? Any advice is apperciated!!
