I've been feeling nauseous on and off, and I think it's because of the combination of taking my bc pill and my vitamin with each other, so I stopped, and I started taking my multi-vitamin hours later, but today, I got sick right after my mutli-vitamin, even though it was during the late afternoon.

Question: are there certain ingredients in vitamins that don't mix well with bc pills that may lead to symptoms of nausea or sickness?

My information pamphlet doesn't list anything about vitamins. It only lists certain medications that shouldn't be used with it.
