Missed a positive ovulation test?

Hi ladies,

I've got a bit of a tricky problem, so I thought I'd throw it out here in the public group. I've tested, but maybe a bit late? See the photo of the tests.
My question is: is this possible, and if so, when would I be due?
My last period was from Dec 25 to Dec 28, usually lasts 5 days but this time 4 days, and I was on cycle day 29 on the first day of my period starting Dec 25.
I think I need a few co-thinkers (hihi) or just people to guess.
Thanks in advance!
