You know when bub has dropped because.....

You can breath easier
You run to the tiolet more
You definatley can`t see your feet,& it feels like your tummy is resting on your knee`s!
and that funny feeling like your bub is going to fall out of your Va gee gee,lol, when you get up to walk.
But your back pain can get worse if you suffer a lower bad back,but it`s funny how most of us go back & do it all over again.
