When is ovulation going to happe.. impatient 🙁

Update:

This is my chart- my temperature tells me nothing im all over the shop. Negative tests but today im squinting and believe i can see the faintest hint of a second line.. (taken 5 mins after peeing/dunking at 17:40) my boyfriend disagrees. im aware its still a negative but its something more than one line! What do you think.. start of something and keep testing to see?
