Soo last pregnancy I was on the same prenatal vits and I had terrible morning sickness and was so nauseous. When my regular multi ran out (around 6 wks) I bought the same type again and began using them. My nausea became much worse over the last couple of weeks. I stopped using them about 4 days ago and have been on my kids chewables until I go buy my regular multi again. My nausea that was getting really bad again has lessened dramatically. There must be a link here! Do you think its the extra iron? Has anyone else experienced this or heard of this? I used different prenatal vits my first pregnancy and had no morning sickness then either. Just wondered if anyone else has experienced this.
