I am just trying to figure out whats going on... about 2-3 years ago, my period stopped showing up. I am 25 years old... my Gyno ran every test under the sun and can't find a reason to why I am not getting my period. Every time she puts me on a medication that you take for 5-7 days to force your period to come, but I would get my period for 1 day after finishing the meds. Well this past time she gave it to me May 2013, my period was refusing to come on even with the medicine, I finially got it after a week of waiting after finishing the meds, but once more I got it for 1 day and never again. Its been a year now since I have had my period.. does anyone else have this problem? And I keep getting told no period means no kids... can crohns make you not have your period? Can it prevent you from getting pregnant?
