I know they are expensive, but I really feel it's worth it to buy the OVK's with the smiley face on them (ClearBlue?). You can use the other test strips for regular testing, but if you are almost positive it is a +, I would use the CB one just to make sure. Because they are individually wrapped, you are not restricted to using all of them in the kit (7) all at the same time/month. You can save them for next month if you have to. Just a thought.

to you!!
