I took pregnacare with no problems for my first two pregnancies - 1 very short, 1 full term. When I conceived earlier this year it suddenly started making me feel sick! I stopped taking them and got BioCare Ante-Natal Forte tablets instead which someone had recommended as a good alternative. These were fine and didn't make me sick at all. When I lost the baby and started TTC again I tried to take Pregnacare again as I have boxes of it in the house! Annoyingly, it hasn't changed and now pregnant or not it makes me sick. I think the only alternative is to swap brand of vitamin supplement and, as above, I can recommend BioCare. You can buy them through Amazon - https://www.amazon.co.uk/Biocare-An...1_2?ie=UTF8&s=drugstore&qid=1282490783&sr=1-2
