BBT help please

Katie

How does this look?? First time of doing this as my cycles seem to be getting longer and longer so wanted to see if I’m actually ovulating or not!

Does this look like I’ve ovulated?? I got a positive ovulation test on Day 31 which I realise is late, last month ir was day 21!

Does this chart look like it’s going to right way?

Will the temp stay high if I am pregnant or will it fall back down period is coming?

Sorry for all the questions!!
