Usually just weigh u an ask u how u feel an sometimes they draw blood... an if ur far enough along u get to hear the heartbeat an measure your stomach
During the first 3-4 months is generally a repeat...urine treat, weight check, blood pressure check, measure of your uterus, fetal heart beat and how you are doing. When you get further along, you'll have to take tests like diabetes snd get blood drawn as well as cervical test, but that's further down the road. Hope that helps...
