The pill

I don't take Aza, but just being sick can mess up your periods. I didn't have periods for over a year when I was very sick (with Crohns) and thin, and we just assumed I reached menopause early, but after I started doing better and put on some some weight, I finally started having them again. The Gyn explained that I didn't have the nutrition to create them when I was at my worse. I still don't have normal periods but at least a get them now. Not sure if this helps, but you know your body best, so if you feel it's the medication Aza, it probably is, just letting you know my experience.

Aw brill thankyou very much! I haven't seen to have any other problems with it againt thank god, I think maybe it was just started aza aswell as being on pentasa and steroids in a flare up just messed it up a little!
