HI all, thanks for the welcome, as I'm new to all this, i find it hard to keep track of who's who's, but I'm sure that will come!
Dawnee-- Months ago when I was trying to figure my cycle out, I bought a book (gotta love ebay!) called "Taking charge of your Fertility" by Toni Weschler, I couldn't put it down I was so captivated to know more about my body, (especially when I thought I knew heaps being a nurse), anyway it answered so many of my questions, I highly recommend it. Though I'm sure there would be internet site links from here which would tell you, not sure. Anyway hope it's of some help.
Good luck to us all!!!
