Thanks for the replies.

I am probably dumb and have worked out it must mean period or cycle returning but what actually does AF stand for?
Also is there a place i can go to find out all the meanings for the letters/initials etc?

Anyway, back to this post.......... glad to hear it does happen, I suppose all we can do is try, hubby will be pleased, the more trying the better

I look forward to hearing some more success stories
