Just a little piece left behind

For the last few months or more probably I have had spotting and horrible cramping on an almost daily basis.
My doctor did bloodwork and when my hormones came back normal, he was content with putting me on BCP's and calling it a day.
I on the other hand wanted to know WHY I was bleeding.
I made an appt with a different doctor who immediately scheduled an ultrasound.
This ultrasound was today, and I had an appt with the doctor immediately after.
I found out that my uterine lining is too thick.
What this doctor believes is that a piece of my placenta was left behind after delivery.
7 1/2 months ago.
Lovely.
So, in a few weeks I go in for a hysteroscopy (anyone had one?) and a D&C to get out whatever is in there.
She said it is most likely placenta. If not, it could be polyps or fibroids. She said if I were older, she'd be more concerned about cancer, but seeing I had a clear pap 6 months ago, she's not too concerned with that. Thanks for even mentioning it, right?
Along with the spotting, when my actual PERIOD comes, my cramps are so bad that I usually spend the first day in complete agony. I'm not exaggerating either. Almost to the point where I canNOT get out of bed.
She feels that seeing we are doing the hysteroscopy, and seeing we are absolutely sure we are done having children that a endometrial ablation would be a good choice.
wee bit nervous of the actual procedures.
Of course I'll be under complete sedation, and apparently recover time is quick and there is a chance I will not get periods anymore. Who wouldn't want that, right? If I do, they will most likely be light. No more flooding.
Being ONLY 28 (how's that for positive thinking!) and having to have my period for MANY years to come, I think that sounds like a plan!
The date is set for September 9th.
So, apparently the HELLP was not enough, I have to go and have PLACENTA left over!
Don't ya think they would have realized that??
