Bella - When AF is due your temperature drops, mine hasn't gone below the coverline yet - if you look at my chart you can see it's dropped the past 4 days and it LOOKS like it will drop again tomorrow, probably below the coverline and AF will start. With YOUR temp rising if it rises again tomorrow and possibly the next day it could indicate O but the difficulty is with having no pre-o temps it will be harder to tell but it will still tell us little bits of info!
Min - anytime, your company last night was a pleasure! I don't know about the O thing, but with the OPK the reason you aren't meant to use FMU is because of the way LH is synthesised. Unlike HCG which is higher in FMU LH isn't synthesised until later so ideally you should test between 11am to 10pm (that's what I've read but I myself have had +OPK with FMU and later than 10pm at night too).
No I don't feel like AF is going to start, I always get cramps the day before she starts or that day and so far NOTHING... I'm totally confused and a little sad too...
