Waiting again -- Updated

I've done 10 days of lu.pron shots. And then 4 more to go before I go in to get bw and another vagicam to give me the green light to start stims.

But I was supposed to start the quasi-period thing a few days ago, and while there has been all sorts of mysterious cramping, there is no sign at ALL that I am going to start to bleed. None. Zero.

I find this annoying and ironic -- month after month of desperately hoping not to see the tell-tale signs of my monthly cycle kicking in and yet seeing it arrive on an annoyingly regular schedule, now that I do want to see it, it's nowhere to be found.

So I'm on what would be Day 31 of my cycle, and nothing. Nothing. No. Thing. Latest my period ever showed was on Day 30. So what to do?

Any ideas? Is it supposed to be later than normal? Normally I wouldn't care about a couple of extra days here and there (yeah, that's not entirely true, but let's go with it). However, we are supposed to travel on Thanksgiving Day, so I don't have a whole lot of wiggle room. Probably not the greatest planning, but we thought we had a big enough buffer.

I sense that I am going to be placing a neurotic call to the RE's office tomorrow.

Argh.

UPDATE (because I'm sure that the rest of you are as gripped by this saga as I am. I am one crazy-ass neurotic woman right now.)

So I called bright and early and spoke with one of the nurses, who are lovely, but usually can't help much. And then I sat around and waited all day for one of the REs to call me back.
And I waited.
And waited.
And stared at the phone.
And waited some more. And stared harder.
And even though it's a mobile phone, decided that I couldn't go to the grocery store, or the gym, or even take a shower because there might be a call, and I wanted to be sure that I was somewhere quiet when it came.
But there was no call.
So right before 5pm closing time, I broke down and called back. No real answer, except I will go in a day early (Wednesday, not Thurs) for more bloodwork and another u/s. Not a very satisfying answer. So I am just hoping my body kicks into gear.
I'd rather lie on the sofa and rest after this exhausting day of waiting, but I have to go to a birthday party. I guess it's good I will leave the apartment since the Boy has told me that my moping is starting to get to him. (Actually -- he'd like me to amend that for accuracy. "Bugging the living shit out of him" is closer to the truth.)
