Too much vomitting 😔

So last night I had dinner and took my prenatal vitamins, after I was done eating.. I got ready for bed. Once I layed down I began to toss and turn 😪 then out of nowhere I literally started to vomit like crazy... I'm sorry if it sounds so disgusting. But I need to know if it's bad to vomit that much after consuming my prenatal vitamins? :/ Doctor told me that prenatal vitamins can be harshly strong that I should try gummy prenatal vitamins. Tried eating cereal for breakfast this morning too and thay didn't go so well either. I'm 11w and 6d pregnant.
