Don't ever stop steroids without the knowledge of and assistance of your doctor. You run the risk of very dangerous and possibly life-threatening side effects from adrenal insufficiency.
Doesn't matter if I am actively flaring, mildly flaring, or seem to be not flaring at all....my "monthly" really messes me up to......my GI suspects I might have IBS in addition to crohn's which aggravates me and creates crohn's-like symptoms during my period even when on prednisone.
I'm not personally aware of your period causing strictures, but I noticed since my last flare I now definitely get arthritis pains in my left hip during my period which I never used to have before. I've gotten a bone density test and things seem to be fine in that area as well.
I know I personally am keeping a special eye on my symptoms during that time of the month and if this keeps happening, my GI says he may prescribe me something to help hold me over during that time of the month.
Women's issues make the body such a confusing thing especially when you are already dealing with other physical/health issues
If you notice your symptoms start bothering you more, call your doc and try to see if you can get your appointment pushed up or if you can be put on the cancellation list to be seen sooner. Or see if they can make a treatment recommendation for you over the phone until you can get into your next appointment.
