I love it. I had my first injection 9 months ago to control my erratic perimenopausal bleeding (my last 2 periods before starting on it lasted 38 and 51 days).
I've not stopped bleeding completely but my periods are very light and last 2 days, I don't get horrible PMT mood swings and spots but I still get tender breasts.
I've not had any negative side effects.
I wish I had it years ago!
