Still Waiting

We're still waiting, no AF and no positive HPT. We're going nuts! R has never been late, not in the 8 1/2 years we've been together. She had open heart surgery a few years ago and that didn't even affect her cycle. Lots of other symptoms but we're not sure if we're noticing them just because we want to. R spotted late yesterday, just a bit of brown blood on the TP (mixed with tons of watery CM, another phenomenon that has been around for 3 days now) when she was wiping, nothing on her underwear. No sign of it since. If this keeps up she's going to go to the doctor on Tuesday. Damn the long weekend!
