weekly appointment help!?

so im 38 weeks 2days and ive started my weekly visits last week but they still haven't checked me to see if im dilating so im wondering when they do that? or am i supposed to ask them to check?i get what i think are braxton hicks,havnt lost mucus plug and literally kinda feel like these appointments are useless they just check babies heart and tell me head is down, like i can check babies heart at home with my doppler and i was already told baby was head down since 35weeks..idk ima first time mom and dont know if this is normal or not
