not true once i hit 37-38 weeks and i started my weekly appointments i got an nst done for 30 mins every appointment its just to mesure the heart rate of baby and contractions if you have some and to make sure baby isnt under any stress. An nst was what made my dr send me to l&d to get induced.. when i went for my nst my little nugget was stressed and his heart rate would drop dramatically then go back to normal so she sent me to l&d they hooked me up there for another nst to see if anything changed and it didnt so i got induced then and there. i didnt have my bags packed or anything. 😷😔
Not everyone gets them. They're usually for higher risk pregnancies or as a quick check to make sure all is good. In all my experiences they do ultrasounds and then hook you up to fetal dopplers and check their heart rate and make sure everything sounds good.
