Bex I've been alternately resigned to the fact I'm not pregnant, and absolutely convinced I am pregnant in equal measures!! 
Had cramps (more than usual, and earlier than usual), which made me think AF was coming. But no sore boobs, and normally they are huge before AF and very tender. Right now, they are normal size and not hurting at all.
Headaches (mild) - but again, could be a symptom of both pregnancy and AF.
Nausea. Had me convinced (especially when my mum frying off chicken thighs nearly made me puke). But then again, had a nasty flu-ey bug which might explain it. Still feeling slightly nauseous.
But what had me more convinced (other than AF being late) was that I have been so hot. Everyone else has been complaining of the cold and I'm there peeling off layers!! And finally (TMI alert), I've had an abundance of CM which is unusual for me. Loads of it and it's creamy and snot-like. Charming! 
Fingers crossed for you - hope you can resist the temptation to poas for a few more days!! xx
