We plan to TTC in about 5 months, and the biggest thing I'm nervous about is side effects from taking supplements. Ever since I got my gallbladder out, my stomach has been a bit sensitive when it never used to be. My dh will take any supplements I tell him to, but as for me, I'm worried. I know I need to at least take calcium, magnesium and cranberry. Have any of you had any nausea, vomiting, upset stomach, stomach pain, indigestion or anything like that from any of them? Are there any other supplements (zinc, folic acid, etc) that have caused any problems?
