Two years ago I had a laparoscopy for my endometriosis and had the Mirena inserted. The doctor started me on zoladex for six months 2 weeks after surgery. That was amazing and I didn't get my periods at all throughout and just assumed it would begin after I had finished. I had spotting throughout the 6 months and a little bit after but then have had no periods since. It has been a year and a half now with no periods. Is this normal with the mirena or should I be concerned this is from the zoladex.
