Depende po how far along you are, they may measure your fundal height po and usually chine-check din ang heartbeat ni baby. If you're healthy naman po, usually hindi rin masyadong matagal ang check up, which is also good para less exposure sa labas ngayong may pandemic. You may also use that time to ask questions about your pregnancy, your baby, medicines, their maternity packages, mga kailangan dalhin, requirements kasi covid (like swab test for you, xray sa kasama mo panganganak, etc). If nakukulangan pa rin po kayo, you can still look for a different OB, choice nyo naman po yan.
if hindi po kayo satisfied, you always have the option to change ob. how about taking measurement of your belly and use of fetal doppler? pwede din na magready ka ng mga tanong about your pregnancy
