FET PREP vitamins

Bre • +FET 💙ZMP 💙DRN 💙MCP Trying for baby #4 soon

During my FET prep, my doctor has me on 4 different vitamins; additional Folic acid, Prenatal vitamin, additional DHA & additional Vitamin D. Does anyone get any side effects from these vitamins? I feel pretty nauseous and just weird after taking them.
