I had my period on the 28th of Jan. it lasted 4 days, was very heavy, (usually pretty heavy with some small clotting lasting 4-6 days) and then just stopped, without tapering off like usual, or lighting in color and flow etc.. it was a bit strange but I didnt think much of it. then on the 11th of Feb it started again, very bright red and HEAVY right away, more clotting than usual and very painful. It lasted this way until Feb 15th. mid day, and the strange thing is that I was using more pads and tampons than I normally do, changing a thick pad every 2 hours or so, a tampon lasting no more than 2 hours. On the 14th I went thru a tampon and pad at same time in 2 1/2 hours. Something I noticed again was before it stopped in the 15th, I had just passed a few smaller clots and very heavy flow and my next trip to the bathroom, it was completely gone! not one sign a period even existed 2 hours prior. I did and do continue to have cramping, stronger than before. I have endometriosis and have had lap surgery a few times in the past. But, my periods are always 28-30 days apart, never have break thru bleeding and never have had 2 periods in one month, never had them stop in a heavy time without tapering off first. I called my GP and she had me take a preg test which was neg as I already knew it would be and said we would just watch and see what it does next month. I cant recall ever having cramps AFTER my flow like this before.
