I would see the doctor to follow up and rule out a secondary condition brewing, They were saying mine was from a fybroid. I have a shot of Proventile B/C I take monthly to help. When I went for the last ultra sound tech said she thought it was not fybroid, and thne they thought about the triggerpoints and steroids for asthma etc...

But Never got an answere why so long, just control them with the injection of c/c...now I am going to be 53 this year, never smoked, tubes tied...but can not stop or the bleeding restarts again for days.

I did have the D&C years ago to check lining for any issues, as it was too thin and could lead to cancer, but last ultra sound in the fall lining is fine.
I just wish I could go through change to stop the shots already....
But, I thought to mention that you may have fybroids, maybe get it checked,
