(((Pam)))
I had to edit this post after reading Di's and an old thread of yours...
I had at first been concerned about a post-op hemorrhage and had suggested ER, but i see now your surgery was last month. so this would be your menses, which were problematic before... So now i don't know.
If the bleeding is excessive compared to before, perhaps ER should still be a consideration.
In any event, I would still call your doc tomorrow and let him/her know this is happening.
i hope you feel better.
