Sorry for FAR too much info but I have passed. Series of large blood clots this evening (3 approx 3in clots) and just now a huge clot as large as my hand. I am receiving fertility treatment (PCOS) and started. Period 8 days ago following a course of provera. Still bleeding 8 days later and now much more heavily. Has anyone experienced this? What was the cause/did the specialist do anything? I have an appointment with specialist on Friday to track any follicles (also took clomid) so will mention it then. Cramps are insane!
