During the test, a stretchy belt monitor will be placed around your belly the same kind doctors often use during labor and delivery. It shouldn't hurt and doesn't usually feel uncomfortable. You've got a job to do: You'll be asked to keep track of each movement you feel baby make.
You may hold a clicker contraption like a buzzer on Jeopardy , and each time you feel the baby move, you'll click it. Other fetal monitors may work differently. And in most cases, your provider can tell you about the results and what they mean as soon as the test is over. A baby who moves a lot and has a normal heart rate is classified as "reactive" — i.
The time increases to 15 seconds if your test happens after 32 weeks. A "nonreactive" baby is one who doesn't make a minimum number of movements during the minute period or whose heart doesn't accelerate as much as expected when she does move. Sometimes babies are just sleepy or less active. In some cases, however, it could mean your baby isn't getting enough oxygen. With a nonreactive result, your provider might opt to do the test for another 40 minutes while encouraging your baby to move more, either with sound, a snack or a sugary drink.
If your practitioner concludes that your baby could be under stress, you might need to undergo further testing like a biophysical profile to determine whether labor induction and early delivery are necessary. The baby might be sleeping, or a more in-depth NST or a biophysical profile might be needed. Biophysical Profile and Amniotic Fluid Index A biophysical profile BPP is an ultrasound exam that monitors the movement, body tone and breathing efforts of your baby.

I am currently 34 wks EDD is May 17th. However, goal is to make it to 37 weeks. Hmm- she was moving like crazy- but her heart beat wasn't changing as much as it should during her movements.
They had me hooked up for an hour and a half- so I know there wasn't ten variations in 30 minutes. Guess we will just see how it goes Thursday. Both of my children have been born right away after NST's. My son was having decelerations that were concerning at an NST and was delivered right afterward at 38 weeks. I'm hoping this baby will be born on her actual scheduled c section date, May 6th, but with 2X weekly NSTs I'm thinking it might be sooner.
I had my first NST last Friday and all was well. The test is safe for the fetus and the pregnant person and usually doesn't take very long. The test might take longer if the fetus is sleeping or not very active when the monitor is trying to measure its heart rate and movement. Your provider will discuss the results of the test with you and make sure that your concerns are addressed and your questions are answered.
If they would like you to have the test again, or want you to have additional tests, they will let you know.
