Missed Ovulation? HELP!

Ka
I've posted a few times now but it's all in bits so I've collated all the data! 
As you can see the strongest surge I've had is cycle day 9 but it wasn't quite positive 🤔 now it's getting weaker so I'm worrried that I've missed my surge! 
Last cycle was my first using OPKs and I got my surge on CD10 so I was expecting it to be around the same and not much earlier as it's almost immedietely after my period! 
Question is, is it possible to have a more positive looking tests, followed by weaker ones and then the surge later? My temps aren't showing a surge yet but again, I haven't been tracking this until recently either. 
I'm so confused right now!!
