I had pre-labour symptoms for so long, I ended up being in labour for two days and not even knowing it - just thought it was all the same pre-labour messing with my head!!
A lot of women say that they get the runs in the lead-up to the big event... I didn't, but apparently it's pretty common, so look out for *that* pleasant sign :/
With me, it was all lower-back pain, right down into my hips and tailbone, and period-like cramping pain in my stomach (which I didn't really recognise because I don't get period pain with AF so I was like 'is this what a contraction feels like?! It's nothing!').
Emotionally/otherwise, I had heaps of energy, but was really irritable - I was soooo hating on DH and DD1 just for being near me the day or so before I went into labour lol - I wasn't really tired (actually, I was pretty wired, I was out shopping and visiting friends while in labour without knowing it, I was running on adrenaline and couldn't figure out why I was so hyped), but I was just snappy, short-tempered and generally feeling *rawr* lol...
HTH!!
