I haven't thought about using the clearblue. I had bought these last year when we were trying(before DH was diagnosed) and never got to use them. They don't expire until November of this year. I think I have 10 or so left so I will need some for next cycle. I don't want to buy in store as they are expensive...do you have a website that you usually buy from?
I always buy them at Wal-Mart, but I guess you could try Amazon.
I look at it this way, they're much more affordable than a child... If I can't afford one package of OPKs every couple of months, then there's no way in həll I'll be able to afford a kid. ;)
