What to expect in the upcoming weeks?

Ive just been reading other posts and some of you know the size of your baby per ultrasound.  Everytime I go to my doctor he just does the Doppler and measures my tummy. Next week will be my 36 week appointment and they said they will check cervix and do some testing. Do I get an ultrasound as well or do they have different ways of determining how big the baby is? Just don't know what to expect at the future doctor appointments... They are changing to weekly as well. I'm going to ask doctor next week but figured I'd ask here to see if there are normal things to expect.
