3rd Trimester Test for Your Surrogacy Pregnancy

It’s an exciting time in your surrogacy journey when you reach the 3rd trimester. Not only do you feel a deep gratification that you’re about to make a couple or individual parents.  Knowing you’re giving them the most precious gift feels wonderful, but also imagine how excited your intended parents are. Don’t you remember having your keeper baby and all the weekly appointments you had with your OB/GYN during the 3rd trimester? Plus medical test you still had to complete before the big day.

Remember all of the prescreening appointments you had at the fertility clinic in order to get you to where you are now in your surrogacy journey. Your surrogacy journey has gone picture perfect thus far, but certain testing still needs to be completed during the 3rd trimester. Several standard tests take place during the 3rd trimester. It’s all typical medical protocol that must be completed. I remember all of the testing I had to complete during my pregnancy. Moving forward 8 years science has evolved and newer advanced testing is offered. Take a look at the  3rd trimester screening and some of the newer advanced 3rd trimester testing offered.

Office Visits and Tests:

As the delivery days nears you’ll go from your once- a -month visits to bi-monthly office visits and then finally weekly office visits by 36 weeks if you’re carrying one baby. If you’re carrying a twin pregnancy your weekly appointments will begin earlier in the pregnancy. At each appointment you’ll do the standard things like getting weighed, do belly measurements, listen to the heartbeat, and blood pressure. You’ll give a urine sample so they can check for protein, sugar and any bacteria. They always want to rule out any signs of preeclampsia or an infection of any type or gestational diabetes.

Group B Streptococcus Test

Your OB will test you during week 35 – 37 of the pregnancy. According to the Center for Disease Control 25% of all healthy women carry group B step bacteria. Most women show no symptoms of the bacteria. If you test positive your doctor will treat you with antibiotics prior to delivery.

 Non-Stress Test:

This test is a well check on the baby. The test measures the fetal heart rate and response to movement. It to reassure that the baby is getting enough oxygen. It’s a noninvasive test and is not stressful!  They call this test “non-stress test” because no stress is placed on the baby.

Kick Count:

Some OB/GYN’s will do this test if you’re not feeling movement or if you’re carrying twins. You’ll lay on your side and records how long it takes for your baby to move 10 times. This test can be quick or it can take sometime to complete. The best time to preform this test is right after you eat because that’s when the baby is likely to be most active.

Biophysical Profile:

This is a combination of a nonstress test with an ultrasound. The ultrasound is looking at four fetal characteristics: breathing, movements, muscle tone, body movement and the amount of amniotic fluid. This test is typically preformed if you’re overdue, having pregnancy complications like low amniotic fluid or decrease in fetal movement.

Cervical Check

Not all doctors will preform a check at each appointment. As you get closer to the due date they might do an internal exam to feel if the cervix has started to dilate and effaced (thinning out) This isn’t the most comfortable exam, but it’s quick.


This is only done during the 3rd trimester if something concerning might have presented earlier in the pregnancy or if the doctor thinks the baby might have a bacterial infection called chorioamnionitis. The doctor will use a long needle to remove a sample of amniotic fluid. It’s a quick test will minimal discomfort to you.

As you can see the 3rd trimester is busy for everyone. You’re running to the OB/GYN weekly plus trying to get yourself prepared for the delivery. Can’t forget that you’re also keeping your intended parents informed of everything going on while there running around getting their lives ready for the big day. Just remember as the surrogate mother to take care of yourself too. You have your own family that needs you.
