Feeling optimistic about this chart

Katie • 27 years old, married
Hi ladies 
​My temps are looking good this month! Last month I O'd on cd17 and this month it's predicted as cd18 which if the temps are right does match (as I stayed high today)
​Hoping that it's actually high coz I'm pg!!! 
​What do you think??? 
​(Green is this month, pink is last and also my first month after BC for 13yrs!)
