Thanks for the info.
My cycle is a little strange, for the bast 4 years I have always got my period on the 25th of the month, I got it one Christmas and ever since then its always been on the 25th, until 2 months ago. Then it came 3 (so the 22nd) days early and then last month it came on the 28th, so I really havn't had a constant length. This is why I thought I would start temping, it's been a real eye opener as I discovered I O a lot eailer then I thought........ so here's hoping this month will be the winner
