Have you tried depo?
I know it doesn't work so great for alot of people, but I'm using it.
Are you still feeding Colby? Its good if your still feeding, but it can make you bleed too
Depending on all the usual things.
Good luck I know that clucky feeling
All my friends keep telling me I should just give up & admit I'll have another one, lol!
(I won't mind you )
