I always thought I had lousy cm too. My RE said otherwise this month when he did the IUI, so maybe we just make so little of it now in comparison to what it was like when we were young that it feels like we make none...it's not really enough to show up outside. Who knows. The point is, I really can't use cm to nail down ovulation either.
I always ovulate on the same day I get a postive OPK or the day after. So as long as I'm positive that I know when I get my first positive OPK, I know I've narrowed it down to only 2 days. You're probably gonna think I'm nuts, but when I REALLY feel like I need to know for sure, which I would if I wanted to schedule the progesterone blood draw, I'd do a couple of things. I'd buy a bunch of regular OPKs - like 2 boxes - and I'd also buy one box of digitals. (I know...expensive! I wouldn't do it every month.) I'd start testing 2-3 days before my earliest O day and I'd test AT LEAST twice a day. The closer it got to my regular O day, I'd even test 3 or more times a day. I'd use the pee in a cup method instead of the in-stream method. Then, when I got an OPK that looked close, I'd do a quick digital one in the same pee and let it clear up the confusion for me. Definitely once I got a "close, but no cigar" OPK, I'd be testing 3-4 times a day if I wasn't already. Once I know I nailed the "leading edge" of the LH surge, I know I'm either going to ovulate that day or the next day (provided it isn't way late at night). It's usually 30-36 hours-ish. That's even more reliable for me than temperature, though temperature can really help pick between those two days sometimes. I don't know if it would work that way for you or not and it's a ROYAL pain in the tush to test 3-4 times a day but when it really counts, to me, it's worth it.
Do you have any symptoms you associate w/ post-ovulation? For instance, many, many months (though not always) I get this "rumbly, grumbly" stomach not too long after I ovulate. After that, I often get a bloated sensation and can start to feel some lower-GI discomfort. It took me months of charting to figure that connection out and then it took even longer to figure out if it meant *impending* ovulation or *recent* ovuation. Ultrasounds helped confirm my belief that it was a post-ovulation phenomenon for me. So I use the OPKs to narrow it down to a day or two and the GI and temp stuff to narrow it down farther. It usually works, but some months NOTHING works! Still - is you can narrow it down to 2 days, you're probably good to go, don't you think?
I know other people who always get headaches right after or who always retain water the day after O. Do you have anything like that at all?
