Morning sickness! Please help.

I'm 7 weeks and I've been taking these prenatal vitamins everyday before bed (ill attach a picture of the brand) I've also been taking vitamin b and unisom before bed because my doctor said it helps with morning sickness! But i still get sick. Everyday. Well i heard the gummy vitamins are a lot easier on your stomach but my question is should i ask my doctor before switching prenatal vitamins or is not a big deal?
