It just crossed my mind, but what if this extended water-fast somehow will affect my IUD? Could my body try to expel it? Or the hormones from it hurt me while on this fast? I totally spaced it off, and I guess it is technically a form of medication, since it is birth control.
Right, yea so far it's never came out for me. However I have heard of this happening for other girls just because, not having anything to do with fasting as you said.
