Can I start using ClearBlue OPK on CD11?

Hi everyone,

I'm currently CD11 or average 26 day cycle. I've been using cheapy OPKs but they're annoying me how inaccurate they are😬 I'm likely due to ovulate in about 2-3 days. I've just bought some ClearBlue Advanced Digital (the 4 fertile day ones). Can I start to use them now or is it too late? I've had a look at the instructions but find them fairly confusing! Thanks x

There's no harm in trying. I have a 29 day cycle and I found that I ovulated on CD 18. Our bodies are not reliable, it changes when it wants. So it's definitely not late. You can start testing today. Let's see how it goes

Thank you @mansah2 ! I've just tested and had the empty circle. I read that everyone gets this result the first time using those ones? My cheapies are getting darker too.

Yes I guess. Usually the test is trying to figure out your normal hormone levels and makes it easier for a sure to be detected. Wishing you all the best
