I had a dnc after the miscarriage of my triplets.
The uterus has a lining in it. "endometrial lining"
what happens is the lining sheds during a womans period.
Over time - that lining becomes thicker and thicker for some woman.
That liner is suppose to shed monthly. But obviously not for all woman!
I can cause very heavy bleeding.
The doctor will go in and and scrape that liner in her uterus.
You can call it a "cleaning".
By the way.... A dnc is a sure way to get her pregnant!!!!!!
So if that's unwanted... Just keep that in mind!!!!
