MyByC,
I use it more out of habit :P
I refuse to pay full price for those sticks because they are somewhat pricey but because I am a poas addict I usually buy sticks half or up to 80% off price. The ones getting ready to expire and they work just fine but the cheap opks are the best I must admit.
Maidenmother you definitely have a positive. Don't rely on CBFM. What you are going through has happened to me before and that is the rea I began using opks. However don't be surprised if you get a late peak. I got a peak two month's ago 3 days after I got a positive opk on my cheapies.
