Oh Sarah, you poor thing!
I can truly say I know how you feel becasue I have just been there and yes, I did have 3 D&Cs! Much as I hope you will not need to.
I had a missed m/c discovered late last yr and 1st D&C New Years Eve. 10 days later bleeding almost stopped but still lots of cramping and feeling "unwell". Scan showed "retained product" which like you. I found such a horrible term considering a baby had once been forming from that "tissue". 2nd D&C with a scan whilst in theatre to be sure all was removed. A week later still not feeling well and a fever -onto three antibiotics!! Over the next weeks still getting some cramping and still quite high HCG levels .Was booked for lap/hysteroscopy to investigate recurrent m/c's anyway and when they looked in my uterus -STILL small amt of "product" remaiing. Had another "gentle" D&C and typical bleeidng afterwards but HCG levels still up over a week later. Somehow in all this I ovulated so eventually AF arrived and VERY painful, with clots etc. Still took awhile for HCG to fully drop but I think the "natural" bleedign was truly what 'cleared" me out in the end. My point in this longwinded story (sorry, wasn't trying to make it about me) was that maybe some of your current bleeding could be AF? Have they been monitoring HCG/hormmone levels.
I think the hospital DR is awful to have said that to you and THEN to say wait till FRIDAY to come in for some answers!! Can you not get some tests,scans etc done sooner?? You should push harder if you are not feeling right. I don't think my Dr believed me when I kept saying things were not 'right' but at least they looked and tested -only to find that my instincts were correct!
Its horrible to have a m/c in the first place but when it drags on and on with complications, it jus makes it so hard to "move on".
Please make sure you get the help you deserve and let us know how things go. I hope things are sorted for you soon.
