Ok. So it's a total accident that I ended up with 2 different kinds of OPKs- clearblue and clearblue advanced. I got a big smiley yesterday with the advanced- wohoo, and today totally expect to get one this AM with the regular. But no go? So I dipped the advanced in the same sample and got the smiley....what?? Am I the only one crazy enough to do 2 or has this ever happened to anyone else....side note- I'm totally getting more of the clearblue advanced ones!!
