Different cycle this time?? Did anyone experienced something similar?

So I’m tracking my ovulation with opk’s since December. We’re I noticed that I usually ovulate between CD 16 more or less.

I always took opk’s for like 5/6 days and could always see the line progression till now I got the peak.

This cycle it is really strange! I tested yesterday at CD 11 and got the FAINTEST line I’ve ever had on opk’s... and today I tested again and guess what... I got my PEAK🤔🤷🏼‍♀️

First picture is this cycle (yesterday and today’s tests) I never ovulated before CD 15 so I’m kind a surprised

This two pictures are from the last two cycles, where you can clearly see the line progression

Today I had also an increase on my CM, felt constantly wet and a lot of egg white cm.

Did anyone else experience cycles like this, with ovulation occurring earlier?

I fel like this could be the cycle 🤞🏻🤞🏻🙏🏻 (at least I hope so)
