Hi, my periods are clotty. I think this has always been the case, to some degree, but after child birth (and after a couple of miscarriages) it seems to be more clotty than usual. Should I worry? So far no problems with the uterus, fybroids, or anything physically visible. Can hormonal imbalances (estrogen/progesterone) cause this? Thyroid/levels was checked fairly recently too, looked fine.
