Hi... my mother has been taking prenatal vitamins for about a month or two... she is not pregnant but her doctor said it's a good vitamin to take.. she is 44 or 45 years old... and as time went on with her taking them she stopped getting her period... and she has been getting chest pains... she said its like a tighting feeling... she has been to the doctor for it her heart was OK I believe... and I know she is supposed to go back for an ultrasound of the heart I think... do you think this could happen from the prenatal vitamins she is taking... or does maybe menopause cause this? Please let me know thanks...
