I am new here..What does EOD mean??
It means having sex every other day. OP, if you're going to take the chance and rely solely on opks then I would have sex for a couple more days. Without temping you cant confirm O. You could be one of those women who O the day of the positive, or even a day later. It only detects the surge. The excuse about an inconsistent wake time is simply an excuse to not do it. It is possible to do with an odd sleep schedule. I am proof of that
I agree that this is often the case. However, I am proof that it doesn't *always* work with an odd sleep schedule - I tried temping for a couple months when first starting TTC, and I was working 50-70 hours weekly on varying shifts. There was absolutely no time of day that I was consistently likely to get even a couple hours of sleep before temping. I tried for a couple cycles, and my charts came out looking like the Rocky Mountains. I gave up for a while, then wound up TTA for a while due to a new job. I just started temping again now that I'm on a fairly regular sleep schedule, and I'm actually getting useful information from it. I think for some, this is an excuse, but for some, it really isn't possible.
ETA: OP, if you haven't tried temping, it may be worth a shot, in case you are in fact able to get some useful information. It really wasn't all that big of a hassle, even on my PITA sleep schedule.
