OPK negative or positive?

Danielle

New to OPK testing and came off the pill 2 months ago so can’t work out my cycles.

Currently on CD15. No EWCM or anything yet. I didn’t get that until CD20 last cycle (but my cycle length keeps changing)

I’ve just done a Clearblue digital (4 day) ovulation test and got the circle/no smiley.

Top 2 (yesterday lunch time and evening)

Bottom just now (just at 10 mins)

Is the bottom positive?
