I tried 3 different kinds of prenatals and I got sick with all of them. I switched to flintstones gummies and I haven't had any issues.
Try the gummies. I had the same issue until I switched. They were the only ones to not make me really sick.
Try eating with or before you take them sometimes a empty stomach will cause that
You are NEVER suppose to take vitamins on an empty stomach, it always will make you sick especially if you are just beginning to take the vitamins .
