Why am I being written off?

Something occurred to me last night as I was having some sharp O pains before bed: why on earth is the doc writing this cycle off? Given my previous 2 cycles where I Oed in the CD 30s, why would it not be "ok" for me to O in the CD 20s? I just looked at FF's chart gallery and there are plenty of charts that show Clomid from days 3-7 (just like I took it) and show an O in the late teens and CD 20s. Granted, I don't know the dosage, but nevertheless, why would it be completely unfeasible for me to O within the next week? Yes, my follicles weren't great on the 3 u/s's that I had, but u/s's are still only a moment in time. I remember when I had a very mature follie and great lining at CD 8 in my unmedicated cycle right after my 1st round of Clomid. The doc was sure I'd O from CD 10-14, but alas it didn't happen until CD 30. So, my body has definitely faked out the docs before.

I am still getting Lows on my CBEFM, but this morning I did notice that the 2nd line is starting to get darker than it has been. I was actually surprised that I didn't get a high. Maybe tomorrow...but even if I don't. I had surprise LH surges and O the last 2 cycles, so I wouldn't be surprised if I Oed even if the CBEFM reads low. I will actually start backing up with OPKs today.

I hope that I really do O soon. The crappy part about next cycle is that Chris will be out of town for 2 days that are highly likely to be my O period if I do end up on 100 mg of Clomid. That would seriously suck....
