I don’t trust first response OPK’s because I’ve gotten positives when I wasn’t ovulating and negatives when I was. I like easy@home brand you can buy from Amazon or digitals the best.

I've had three positive opk in the blue test but this negative one in the pink dye

From the blue dye: +O. Pink dye:-O.

I use the Accumed brand for both LH and HCG test strips. Good luck!!

First response opks suck. You're ovulating !!

These are opks!!

Are these ovulation tests or hcg?

Don’t see how it’s different results they both look positive to me
