Polycystic ovary syndrome

Had our first appointment today, heard the baby's heartbeat! We are at 6W 4D :) the doctor thinks that I may have PCOS due to my irregular periods, and stated that it is usually hard to conceive or get pregnant at all, well hard part is over, we are pregnant. She told me there is nothing to be concerned about, but being my first pregnancy I'm still concerned. Any tips on this or things to do while pregnant?
