20 wk check up - what to expect?

[chocolatecatty]

Hiya ladies,
I have my 20 week check up on Wed. and was wondering what to expect? My first check up was with a midwife, but this one is with the gyno/ob guy....is it just a lot of questions and answers or will there be examinations?
Thanks.
ps: isn't it just weird how many celebrities have had babys in the last two or three weeks? There's about five! Talk about group planning......
