What are the best OPK's?

[Tinks15]

Anyone recommend which ones to buy?

Personally I'd go for clear blue dual hormone. X

I use Clearblue Fertility Monitor. I have the old one. You can pick them up really cheap on eBay, or the newer advanced model for a bit more.

Otherwise, as @Hulaballoo said, the Clearblue dual hormone is good.

Do NOT waste your time with anything that isn’t the Clearblue Smiley indicator one.

Other OPKs for me were bobbins and gave false reads.

Spend the cash and read the instructions. I did 10 months ago and I’ve just welcomed DS into the world x
