What do you think if this chart? Does it look ‘normal’? Or is it erratic ?

First proper time temping so I’m new to it

Got a positive OPK about 5 weeks ago but I have pcos so it could have been a false positive

Pregnancy tests are negative and obviously my cycle is long and erratic

I have no idea if my temps are normal or erratic or what they mean! Still trying to learn I’m after any advice and opinions

Thanks
