I had a miscarriage at 17 weeks on 1st November this year, during my labour I passed several large blood clots. About seven hours after delivering both the baby and placenta I passed another blood clot about the size of a dinner plate. I woke in the early hours of this morning with a sharp sabbing pain in my lower left side, the same pain I had before I went into labour I am now passing blood clots about the size of an egg about every hour along with a gush of blood, what could be causing this stabbing pain? As it is only on my left side and what is causing the bllod clots?
