It took about 4 weeks for me. Unfortunately, I had an incomplete miscarriage, so things got pretty complicated. Thankfully it all came out after I developed PID. *grumbles*
And I'm going on week 7 of spotting. *more grumbles* I'm unsure about the ovulation question. I have heard it both ways.
To Welshdee: I really hate to hear of your loss, and I hope it all comes out soon! It's such an awful thing when it's so long and drawn out...I almost went nuts! Make sure that if you have any bad pelvic pain, you go straight to the hospital! Where mine was incomplete and sat in there so long, I got an AWFUL infection and had to stay in the hospital for 3 days! It really sucks that you have to wait that long! Good Luck and try to keep your head up!
Sticky baby dust to you all!
