Positive OPK 4 days after peak?

[WaitingForLittleSunflower]

Another post from me, sorry 🙈

I am driving myself crazy so I'm hoping someone can help explain what on earth is going on!

I had a peak CB ovulation test on Sunday morning (cd13) my temp had dropped on cd12 and then went up cd13 and c14 and then dropped again on cd15.

I did a cheap OPK this evening and it gave a really strong line..I'm currently cd16 so have no idea if I've already ovulated or not??

I thought that because I had my peak on sunday morning, I would have ovulated on Monday or Tues at the latest?

Any insights would be so helpful!!

I had a "peak" high in my last cycle, then carried on testing to watch it. 6 days later I got my true peak and ovulated... apparently can be common as a practice one a few days before the real thing if your body didn't manage to release the follicle!
