Thermometer question and chart

I took everyone’s advice and started using Fertility Friend, what a fantastic app! Really answers so many questions and is so informative.

Question: the very first temp I took this morning was 35.49 but I was half asleep (I put an alarm on to take it the same time every morning) I kept opening my mouth by accident and so I took my temp again straight away and it was 36.57, I then took it 3 more times to make sure it was the same and it was. All temps taken within 15 minutes from the first one.

If I put the very first temp in Fertility Friend it doesn’t flag any ovulation but when I put the second temp it does flag ovulation (which matches with my clear blue digital advanced and positive opks etc)

I had wet CM (not quite stretchy egg white) on the days predicted days of ovulation also.

I’ve bought a new thermometer now, as I’m worried there’s something wrong with mine now.

Here’s my current chart below using the temp 36.57:
