Having been thoroughly disappointed with the wonky behavior of the ClearBlue Fertility Monitor, I ordered some Wondfo brand OPKs. (Also, I'll be traveling during ovulation this month and didn't really want to take my monitor with me.)
They arrived today but didn't come with any instructions and I'm wondering if you have any tips.
On what CD should I start?
Do I test once or twice a day and when?
Is there anything I should know about reading the results?
Would love to hear about your experiences with these...
Thanks!

It's my first month temping as well, do I'll admit that I'm keeping a Wondfo "journal". I'm in CD11 & still no positive, but I'm starting to feel O aches, so I'm anxious to see if I do get a positive Wondfo.
@Rumbera28 I learned something new today. I didn't know as you aged you have more LH in your system. Consider me edumacated!
