Just been to boots and while i was there i saw the digital thermometer and fertility diary they have thought £12.99 was a bit steep for a little book and a digital thermometer when i have seen them for £4.99 but got it anyway and its ace! It all comes in a really neat little organiser. I wasn't expecting that but its pretty cool. Will also keep it discreet which is great cos don't want to scare dh. He knows i have been taking my temp but i don't think he knows why though.
