They will most likely weigh you, check your bp, do an internal to check your cervix and probably a pap smear as well. They will ask you the first day of your LMP and do your dates from then, so if you have a longer than usual cycle (meaning you may ovulate late) I would let them know. They will prob suggest a hospital to book into, and talk about nuchal tanslucency scans - they may send you for a dating scan as well. Depending on how far along you are you may be able to hear the heartbeat as well. Write down all the questions you want to ask about food/exercise/sex/spotting/anything else, because you will forget on the day. Hop eit goes well.
