I've been to so many gyno appointments, and I've never been examined by any of them! I wouldn't worry - even if they do examine you, you won't be the first who's had their period at the time. I mean, don't they hafta do 6 week checkups for new mumma's? Surely some of them are still bleeding post birth

ETA - That's weird BG, my last pap was done in the ER during my last miscarriage, they never said anything about the blood corrupting anything...
