Questions for those that have had surgery before...

I guess the title says it all, huh?! I just have a quick question before I have to run out and get some errands done (we are almost all settled in at my GM's house, house hunting with resume again next week after I'm feeling better.)

Of the ladies that have had surgery done, whether it be the ovarian drilling, wedge resection, removal of endometriosis, or anything "down there"...how long after before the spotting stopped? I had the surgery last Tuesday and I am still having some spotting, mostly brown. It's not a whole lot, but it's more than I have had before and although my doctor said it would occur, we never thought to ask how long.

Thanks ahead of time to anyone who can shed some light on this for me!
