I didnt have many symptoms at all until about week 37.
Boobs would only leak if i squeezed them, no waddling, slight swelling and i felt great.

in this last week boobs have become firmer and hurt - like pre AF, i waddle like you wouldnt believe (this is because bubs is now fully engaged) and have swollen dry feet and the list goes on.
Dont worry - your body knows, enjoy it while it lasts... I did!
