I haven't seen anything against the urine tests, Eliza. I imagine they're probably just as accurate/inaccurate as your average pregnancy test. But they look like they could add up, moneywise, to me. If it were me, I'd probably start with a digital thermometer, and when I had an idea when I was likely to ovulate...move to the dipsticks (actually what they're callled, gotta love that) to pinpoint when I was ready in any given month. But that's just me.

On the OJ front, aren't women who are trying to get pregnant supposed to be drinking lots? Not to help with the pregnancy odds, but because having plenty of follic acid around early in development was protective against certain birth defects?

You might check to see if there are duolas or midwifes in your area....they're usually more than happy to talk to people before as well as during pregnancy, and they'll be able to help you sort out all the alphabet soup on the sites you mentioned.
