Ok so my doctor told me to start taking a daily vitamin to add folic acid to my body so I did. But now my extremely light and short lasting period jumped back to a 12 days of menstation. So I stopped taking the vitamins When I was done I had an appointment for an hsg test and they told me that spotting is normal. My spotting stopped all together within 8 hours of my appointment. Yesterday I decided to start taking the vitamin again and suggested and my the evening it was like my menstruation was trying to start again. Has anyone else ever had something similar to this happen to them? Has bleeding stopped and then started again after an hsg test to anyone else or could it be the vitamins?
