When did my surge start?

[HopefulPony]

So I'm in a bit of a confusing place cycle wise, thought I had already ovulated, but apparently it's happening now. I won't be able to get a sperm donation until tomorrow which is worrying me a bit that it'll be too late... here are the tests, when do you think my surge started?

The bottom test is this morning's, the next one up is yesterday afternoon and the next one up is yesterday morning.

Also to add I have had EWCM for the last few days on bucketloads, but it appears to be creamy now!
