I asked my Endo at CD 12. He didn't comment that it was out of the ordinary, told me to ask my GYN, and said I would probably return to whatever my cycles were once hormone levels were regulated. The problem is, my first appointment with my new GYN dr is not until the end of Jan. (I stopped seeing my other, we didn't mesh.) I could call and ask my GP, I guess.
Everything I read online said it could cause menstrual changes, but didn't specify it would be this long...
