I really don't know, Chimp...now I've found out my cycle was 28 days, not 29, as I previously thought (thanks to an informative thread on here) I'm due AF on Weds. So I'm now considering a test tomorrow.
I've had such a weird cycle, including ovulation bleeding, then further spotting at the potential implantation time. And now cramping and back ache, with heavy boobs / itchy nipples and mild nausea.
But I am seriously trying to read NOTHING into the oddness, as it could be anything, bearing in mind it's all hormone-related!
It is very odd for me, though. I just don't do physical AF symptom build up. Never have!
I'm not that tired though (no more than usual, anyway, but I'm always running at slightly tired thanks to early starts and busy days). Apart from today, that is...no energy at all at the moment. H2B even cooked our roast (under instruction!).
