When the results came back normal, she ordered progesterone to reset my period to normal. But before I had even taken the progesterone, I got my period, and this time it was mild; the next month, it was mild again. I told her about the postpartum waterfall periods the year before and my GP’s insistence that a missed period was no big deal. The symptoms of POI are generally the same as those for women nearing menopause; they just happen earlier than usual. Like menopause, POI can increase the risk of weakened bones, fractures, and heart or blood vessel disease, and the longer you go without enough estrogen, the greater the risk.
