Sickness

I am only 7 weeks pregnant and I feel nauseous 24/7. I have yet to vomit.. but today maybe an hour after I took my prenatal with my breakfast, I did. TMI but it tasted/smelled just like my prenatal. I'm wondering if that's why I vomited, I've been taking them for maybe 2 weeks. I just don't know if I should switch to a different prenatal or just deal with getting sick :(
