Bean and LLPM, thanks! I'm not concerned, I just want to feel pregnant! My beta was 590 at 4w5d. That's low (not out of range, but pretty low), but it was up from 57 5 days before, which means it was more than doubling every 48 hrs. It's possible I'm only actually 4w2d (that's what FF gives me if I discount my OPKs), which case my beta would be perfect. Mostly I would just love to be in the second trimester all ready ... have a bump and feel the baby kicking and all!
LLPM -- to get a clear picture of when you O, you're supposed to have 6 temps before O (FF looks for 3 temps that are all higher than the previous 6). So you might want to start temping a few days before you expect EWCM if you really want to know. But the every other day works perfectly anyway, if you're not too concerned about knowing just when you O'd.
