How To Know And Calculate Gestational Age?
Good morning …. My last menstruation was August 4, 2018. But on September 2-3, I had a testpack with 2 very clear lines. After I had an ultrasound, it turned out that my fetus was only 2 weeks old. Is that normal?
Hello Shelly Ashfia
Thank you for using the consulting services at HealthReplies.com
Pregnancy occurs when the egg meets sperm in the fallopian tube, which forms an embryo, which is implanted in the uterus. Pregnancy has a high chance of occurring when the fertile period arrives. The fertile period is related to a woman's menstrual cycle. Related to the age of the womb, it can be calculated using various techniques, including:
Based on the first day of last menstrual period (HPHT): gestational age is calculated based on the first day of menstruation starting with the last menstruation experienced. It needs to be re-ascertained whether 4 August 2018 is the first day menstruation begins or the last day menstruation ends in that month. Based on ultrasound examination: until now the calculation of fetal age is more accurate using ultrasound, especially in early pregnancy. Testpack is a tool for testing pregnancy by utilizing the HCG hormone in the urine. Human Corionic Gonadotropin (HCG) hormone is a hormone produced by the embryo so that it can attach to the uterine wall as a place for fetal development for the next 9 months. HCG is generally detected 7-14 days after a fertilized egg has attached to the uterine wall. When the pregnancy testpack is positive, it is likely that pregnancy has occurred. Therefore, it is necessary to confirm using ultrasound to see the embryo sac that has formed in the uterus. The fetal heart rate will be read by ultrasound at 6-7 weeks of pregnancy. Subsequent evaluation of pregnancy using ultrasound to assess fetal development.
So much information I submit. If there are other complaints related to your pregnancy, I recommend that you check with a gynecologist in person to get more complete information and management. I hope this helps.
