HELP opk confusing 😭

So, buckle up 😂

I have 26 day cycles. I tend to ovulate on CD15 every cycle.

This was my first month OPKing, so I started the day after AF finished.

This was 2 days after AF finished.

Then nothing on the the rest. Until CD14 & CD15 I got this. Along with usual ovulation cramps. So u ovulated as usual on CD15.

And I’ve been BBTing for the first time too. As I can see I spiked at ovulation. So that confirmed it. Then, this morning at 6dpo, I spiked again... bigger..

And I had slippery CM for the first time this cycle last night and this morning. Strangely at 6dpo?? So that plus my weird spike in temp, I decided on a whim to take another opk. I don’t know why 😂 and this is the result

Whaaaaat is going onnnn???????

Positives after AF. At CD15 with ovulation cramps and again now 6dpo with slippery CM???

Help please x

I’ve been googling it and apparently this could be a sign of pregnancy? opk can pick up on HCG or estrogen surges from conception? My AF is due in 5 days... Anyone??
