Congrats and welcome to OB!  You might find 
this thread helpful, it's a similar question that was asked recently 
How quickly you need to find a midwife depends on where you are in NZ but in lots of places you do need to start looking straight away.  You may like to go to your doc to confirm and get first blood test etc but you don't have to.  Hope that helps 
FYI there's also a thread listing some common abbrieviations etc and questions often asked in the community 
here which you might find useful as a newbie
