Best wishes to you ickimum!

Hollye - a web site called Fertility Friend is very good with helping understand your temp charts and how to go about it, and you can buy good thermometers from the chemist. Basically, you take your temp upon waking in the morning, before you sit up or move etc, and you record your 'body at rest' temp. Temps rise around ovulation, and usually stay high until AF arrives, then drops again - or they stay high if you're preg!
Hope you get good results from your blood test
