Health Care

i didnt know where to put this.. but im not from out here im from Arizona i moved out to mass when i first got pregnant. so i couldnt be seen until i got mass health. i signed up and now i can be seen but they keep saying i need a referal or physician. i dont remember which one they said but its so it covers my pregnancy and i dont know how to get one. in arizona i didnt need to do any of this😯 or my dr said i could add another health care with the masshealth so i wont need one. can i get some help ? no judgement please
