Hi, I have just completed my first trimester of pregnancy. I have been advised to take LivogenXT 1 tablet daily, but everytime whenever I take it, after sometime suddenly I start feeling nauseatic and vomit out within one hour (dirty black color). It has been just three days of medicine intake. First day, I took it before sleep, I felt uneasy, but slept. On the other two days, I tried it during daytime, but vomited. Please advice.
