I'm 12 weeks pregnant and so far I've only seen my normal family doctor. He check fetal heart rate but that's it, should I be seeing anyone else?

I'm 12 weeks pregnant and so far I've only seen my normal family doctor. He check fetal heart rate but that's it, should I be seeing anyone else?

I suggest "yes": Unless your family doctor has an active obstetrical practice - delivers babies and sees patents for prenatal care - you need to start seeing an OBGyn or provider who doe these things. In some communities family docs do obstetrics, but unless yours is one of them, you now need an OB doctor, not just a "doctor." Good wishes. ...Read more

What is a non-reassuring fetal heart rate tracing?

What is a non-reassuring fetal heart rate tracing?

Babies tell us a lot: Monitoring a fetus by fetal hr, ultrasound or the expectant woman's perception of activity is important. No one test can tell us everything we need to know, but together they can tell us which babies might be better off delivered. If a baby is near term and the testing is worrisome then obstetric specialists or subspecialists might deliver. But conditions can change. Plus every case is different. ...Read more

What is the definition or description of: abnormal fetal heart rate?

What is the definition or description of: abnormal fetal heart rate?

<110, or >160 bpm.: After the first trimester, the fetal heart rate should fluctuate between 110-160 beats per minute. Arrhythmias (skipped beats, tachy-/brady-arrhythmias) account for most pre-labor abnormal heart rates. Intrapartum fetal heart rate depends on fetal oxygenation and placental perfusion and is used to prevent death of brain injury during labor. Decelerations may be early, variable or late. ...Read more

What is the likely explanation for low fetal heart rate during pushing?

Head compression.: Typically, the fetal heart rate decreases episodically with contractions during the pushing stage of labor as the fetal head is compressed and rapidly descends in the birth canal. Head compression causes a parasympathetic neural discharge that slows the heart rate as long as the intracranial pressure continues. Other causes: cord compression, placental failure can also occur. ...Read more
