Last three cycles I’ve used the CB Digital Advance OPKs and First Response Standard Fertility.

You’re probably wondering why both. I had a miscarriage in July and it threw my cycles all off. Before the pregnancy My cycles were very regulated and ovulated CD15 like clock work.

I was using the CB and would get early ovulations on CD12. Didn’t seem right so went out and got standards and they confirmed CD15.

This happened two of the three cycles, only one month matched. First month it happened I wasn’t temping. This cycle it happened again and I am temping (glow has one ovulation date and FF has the other ovulation date) both can be confirmed with temps. I can attach charts if needed.

Long story short: what OPK do you recommend? I’m at the verge of getting up on OPKs?
