Multivitamins & vit D

Anyone taken multivitamins & vit D from 12th week onwards and had diarrhea? I've been having diarrhea ever since starting vitamins and it's so concerning as I pass out water at times (no stool but just water) 😭😭 Tried skipping the vitamins all together and no diarrhea. Should I stop and monitor & bring this up to the doc during my next check up or do I continue taking it? Ps : this is also my first time taking multivitamins for this 2nd pregnancy- didn't manage to take multivitamins for no 1 as I found out I was pregnant in the end of 2nd trim.
