Good afternoon, I am a mother who is expecting a pregnancy of approximately 3 years, and this year thank God I was given trust by God. I want to ask, I last menstruated November 16, 2018 and the midwife’s calculation was more or less the age of the fetus I was 15 weeks, but when I was ultrasound there was no size for 15 weeks, around 11-12 weeks, and the heartbeat was not heard, that’s what it is, reasonable thing / not?

Hello Celiz!


Thank you for the question on HealthReplies.com,


Please note that the development of organs in the womb will occur with the development of gestational age, the development of the heart organ begins to form after the age of 4 weeks of pregnancy. However, the development of a fetal heartbeat can be heard as early as around the 8th week of pregnancy. To determine the gestational age you can use the estimate from the First Day of Last Menstruation, determination of uterine fundus height or uterine height from fetal development, as well as by using ultrasound. The search for fetal heart rate / DJJ can also use several methods, namely the Laenec stethoscope, Doppler, and at the time of an ultrasound examination.


Fetal heart rate can be heard as early as 8 weeks using ultrasound, but in general fetal heart rate can be heard clearly at 16-18 weeks of age using Doppler examination. In determining the gestational age using HPHT, High Fundus Uteri, and USG can be found differences in gestational age but in general can use a benchmark from USG to help determine gestational age and estimated fetal weight. Can carry out periodic control on obstetricians during the antenatal period and visit on schedule or earlier if complaints are obtained.
