I didn't really stress too much temping. I think that, for me, it took AWAY stress to know what was going on with my body--maybe out of curiosity, but also to have a record to show the docs when I needed to. Then I felt like they couldn't tell me that partial charts meant they had nothing to work with and come back in a few months. Grrr...
I know that lots of women do only partial charting and it works well for them. If you choose to do it, I hope it works for you!!! Maybe DH SHOULD hide that thermometer after you O! (No temptation...)
