I am a 34 year old female. after my last baby was born, 5 years ago, my periods became completely regular every 4 weeks about 14 months post-delivery. About 3 months ago, they have still been regular but ridiculously heavy..approx 2 super-plus tampons every hour on day 2. About 7 days ago, when I was due, like clockwork, I had terrible cramps, as usually, mild spotting day 1, as usual..period never started. I am not pregnant, my husband had a vaesectamy.
