Provera period...clot size.

Stephanie

HELP! I've been having irregular periods since stopping BC in January so my OB prescribed provera five days a month. Anyhow his is my first period on it and I swear I just passed a clot the size of an ork booger. Is it ok to pass one that large? It was the size of a tangerine? Could it just be that I'm quite literally "cleaning out"?
