Hi! I had my LEEP done July 6th. About nine days after I was changing to leave work and felt a very large clot pass. I decided probably not that serious changed my pad and drove to a friends house, when i got there i was soaked, completely. She drove me to the ER and I waited for what seemed like FOREVER to see the dr. They had to changed the four pads under me about 10 times because they kept soaking with blood. The dr finally came in and explained that this is pretty common. Basically they Cauterize (kind of like when you burn the end of a rope to keep it from fraying) the area of the LEEP afterwards and that wears off so the area starts to bleed. By the time she came back to do a pelvic exam the bleeding had stopped.
Believe me I know how scary it is to be basically covered in blood. Just letting you know, this is like three days after your post so I'm sure everything is okay now!
Good luck to you! Hope your dysplasia does not reoccur
