something like globs of black cherry jelly or other lovely shapes?? if you use a tampon they are stuck to the side of it, or sometimes you can pee and they slip right out and slide down the toilet. hate to be graphic but ive had them and i have them right now acutally. and i notice the really bad cramps like make the clots come and are connected somehow. i have some built up lining to git rid of, and apparantly your uteurs contrancts(cramps) and pushes/sheds the lining out- i apparently have lots. Its nothing to be concerned about although id have to say it looks pretty grim, and it will settle down eventually. if something feels really wrong with you body and you have it everyday for a month or soemthing than i would talk to the gyno but its just something we gotta deal with untill were all evened out!
