Pro biotic causing nausea & vomiting

My midwife suggested fem dophulis and I've been taking that since the 1st of my pregnancy, but switched to ultimate flora last week because I ran out and figured this would do the same thing... big mistake. I'm convinced it's the probiotic that's making me puke again. I went from taking one anti nausea pill in the morning to three throughout the day plus vomiting at least once a day. 😣 I've always had a sensitive stomach to vitamins and stuff. Anyone else?
