Any idea what’s going on?

I typically have an average 30/31 day cycle. But it’s been as low as 27 before and as high as 40 before. This is my first cycle using opk strips so I didn’t know to stop testing after a positive 😬 and now I’m confused.

CD 10 creamy cm

CD 11 ewcm/watery cm

CD 12 watery cm (pinching pain on right side)

CD 13 watery/creamy (kind of a mix)

CD 14 watery

CD 15 couldn’t tell

CD 16 couldn’t tell

CD 17 creamy

CD 18 can’t really tell 😅 (feels like mild af cramps)

Do you think I should count cd 12 as a positive opk? Or do you think my cramping today is ovulation coming up?
