Thank you ladies!
From what I have seen, it does appear that the Mirena is my best bet. And anything that makes AF lighter is good by my book! lol
Will have chat to the Dr next week when I go in for my PP check-up.

PO5 - I am sure we will end up with him getting one, and it will be nice not to have to worry, I think I just need some time before I can ask him to get it done. lol

ETA: Polly - how do they put it in? Is it a general or a local?
