I'm 34 weeks and I got pregnant through ivf. I went for a non-stress test and to get my fluid checked since I'm high risk. While doing the non-stress test they found that the baby's heart was skipping a beat at times, but it didn't happen a lot. They said this can happen if the heart is not fully mature. They wanted me to do a more involved utrasound to check it out and to measure the baby again. The mesurements were good and the baby is 6 pounds 3 ozs now, but the found a membrane that was in the same sac as the baby. They said not to worry, but I'm worried. I don't know what it's from and it kind of scares me. Now, for the next non-stress test they want me to do another utrasound. I just don't want anything to happen to my baby.
