Opk positive???

I am so confused! On cd 9 i got a positive opk on clearblue advanced digital (i was told it was best for pcos). CM was eggwhite. Obviously bd on cd 9-12. Idk why but i have kept testing opk (probably a little addicted 😂) anyway cd 11-14 negative. Today cd15 still testing I get another peak fertility. Cm is more creamy than egg white.

Anyway my question is...

Has anyone ever had this happen before? We are going to bd just to be safe but I have never had 2 positives in the same cycle.

I also read that if you got pregnant and continue to test you might get peak fertility again with these. Has anyone had that happen?
