Starting when I was 47, I stopped menstruating completely (not even a tiny bit of spotting) for 9 months. I was sure that I had hit menopause. But two days ago I started menstruating "full speed ahead" (I've always had very heavy periods). This is disappointing, puzzling and somewhat alarming. I took augmentin for an ear infection several weeks ago, which made me very sick and caused me to develop a yeast infection. I have also been under a lot of stress lately. But except for those two things, nothing else has changed in my life. Should I be worried? Is this common? Do you know what could be causing this? Is there any hope that I will return to my happy menopausal state?
