21 wasn't my friend.

Not this month, anyway. Another negative OPK tonight, but with a darker line than yesterday. Does that just mean my follies are taking a long while to mature? I'm just confused. My hubby also wondered and put in my head if maybe the electronic thingy that reads the test may be bad? I don't think so, because it does all the normal things, but I'm using my one from last cycle. Anyway. I only have one stick left to pee on, so it better be tomorrow!
