OPK newbie help please

[TickTockBaby]

Hi all,
Looking for some advice to whether this OPK is positive?
It's my first attempt at using them and I'm a little unsure of reading them.
This is definitely the darkest it's been but not quite sure if it's positive.

Any advice appreciated 🙂

Not quite a positive, looks like it might be tomorrow though, good luck!

Ahh thank you! 👍
Will keep POS 🙂
