Sense of smell becomes like some kind of sniffer dog and the smell of leather makes you throw up (particularly bad when you have a leather sofa and leather seats in your car).
Sciatic pain so bad that couldn't sleep at all from 7 months on.
Ankles and feet swelling to three times normal size.
Carpal Tunnel so bad have to wear wrist supports at night with metal plates in to stop hands bending.
Any sexual urges would completely disappear.
That being induced is the most hideous thing in the world (especially when it doesn't work the first two times).
That you can't take antihistamines when the pllen count is ten zillion.
Hair changed colour at about 8 months from blonde to brown(don't see anyone else saying this one)
And finally - Never believe the radiographer who tells you the baby is perfectly normal sized at 37 weeks when the MW and OB are saying otherwise - it will be over 10lbs, take you two days to squeeze out and leave you with a third degree tear
I am sure there were some nice surprises but I can't remember them.
