dma, we are pretty much in the exact same situation. The only difference is that I don't really have any PCOS symptoms (that I know of). This is my seventh cycle trying, I've been using OPKs & charting to confirm O every cycle, but despite pretty good BD timing, I'm not getting pregnant. My LP is consistently only 9-10 days. My BF got a SA & it came back pretty normal across the board. Nothing to write home about, but no real problems either. I've been off BC since October 2010 & haven't had an HSG done (waiting to see if Clomid works its magic first).
My ob-gyn does fertility counseling as well, & she started me off on 50mg of Clomid, days 5-9, no monitoring (aside from pre-Clomid bloodwork to rule out other issues, like elevated prolactin, etc). She also put me on progesterone supplements, which I started on CD17 (the day after I O'ed). I think the idea is that the Clomid/prog combo will give me a stronger O & the hormone boost I need to allow a fertilized egg to implant. I guess the idea is that I'm releasing eggs, maybe they are even getting fertilized, but they can't implant because the short LP means the endometrium is breaking down when the egg is ready to make itself cozy.
So right now I'm 7DPO on my first try with all this stuff.
Quick question: do you know what bloodwork you've already had done? It sounds like you might indeed have a prog issue, but that can only really be ruled out by bloodwork during your LP or via ultrasound to check out the endometrium (also during your LP). Has you doc done that? If you've only had FSH & prolactin & all that checked...well, that doesn't give any definite info on prog.
I think every RE has their own style that makes them feel comfortable. Some seem to be all about monitoring the follicles even if the patient isn't doing IUI. I mean, go for it if your insurance covers it, but it kind of seems like a waste to me. The only thing I'd press with the RE is that 1) you're ready to try medication, 2) you're concerned about your LP, & 3) ask about prog supplements. & double-check your prescription drug coverage because the go-to prog docs seem to like to prescribe is crazy expensive. There are generics that work just as well.
