Need help reading this

So I still don't 100% understand how to read this. So if you want to help me pinpoint ovulation I would appreciate   it. Also if it didn't take when would I see a tempeture drop? I still have one week til my monthly.( I'm excited but same time worried. My husband just found out his week that he will be losing his job in the next 6-9 months a small part of me wants it to take the other would be relieved if it didn't.  ​
