Hi Gill. I did the temperature thing when I fell pregnant with my first and although it was a bit of a pain, it becomes part of ones routine and it is all in a good cause. As it was I didn't really need it in the end as the first clear month (I started part way through a month to get into practice) I fell pregnant anyway, but I was able to pinpoint when I ovulated. Give it a go, it works out a lot cheaper than ovulation kits and there is no peeing on sticks! And you do have a written record of what has been going on if you do need to resort to going to see the doctor. Good luck! N. xx
