In progress, 4 measuring points. Description: The first day was very heavy and came on suddenly at 5am. No light spotting or a few cramps for a day or two as usual. I literally was woken from a dream that I was wetting the bed (which I had convinced myself in the dream that this must be what was happening since I knew I wasn't on my period and couldn't be leaking from a heavy flow day; I lucid dream frequently) to spasming expulsions of very large amounts of blood. I normally have heavy flows but not this heavy until around day three and never this sudden without any previous symptoms I was about to start. The consistency was very thick almost syrupy with large clots and what looked like whitish swirls throughout it. Also, the cramps began with the blood and were constant and so painful they made me feel as though I might throw up, pass out, and felt as bad as the worst painful diarrhea cramps but definitely located in my uterus; it felt as if someone was squeezing it like and orange and never releasing the grip. So far unlike any period I've ever experienced.
