Calculation Of The Exact Gestational Age?
Good night doctor, in November 2017 I forgot my period or not, because since marriage I have had irregular menstruation, the date is not correct, like when I was a girl, in December my 4th was like menstruation but only three days, the blood was not much, which I want ask if when I thought my period was actually already pregnant? Because on January 16, 2018 I just found out that I was positively pregnant, but what I was confused about was my pregnancy age, how many weeks / months I was confused, because the midwife asked me when is my cellphone? I answered December 4, but to be honest, I still wonder if I was actually pregnant on December 4?
From the information you have given, the existence of a history of irregular menstruation can indeed be an obstacle for pregnant women in determining when the last menstruation was and the estimated age of the current pregnancy.
However, judging from the information you have provided, on December 4th with a little bleeding that lasts a short time may be a sign of the beginning of your pregnancy. However, this condition needs to be confirmed directly by your gynecologist.
To calculate gestational age, apart from using the hpht calculation, ultrasound examination can also be done to calculate the estimated gestational age based on the length of the femur or the circumference of the fetal head.
In addition, the estimated gestational age can also be calculated by looking at the height of the uterus. This can be done by the midwife or based on the results of your obstetrician's examination.
Therefore, in December you may have started getting pregnant, and the possibility of your pregnancy has entered at month 7, but you need to confirm this estimate directly with your obstetrician. During pregnancy, you can do at least 3 times pregnancy checks to the obstetrician, in early pregnancy, mid, and near the time of delivery.
That's the info we can convey, read also Calculating gestational age.
