How To Find Out The First Day Of Pregnancy?
Assalamuallakum …. Want to ask like how do you know the first day of pregnancy. Is the first start of menstruation or the last day of menstruation. Please clear mom, right?
Basically, the first day of pregnancy starts from the fertilization of the ovum cells by sperm cells. However, until now there has been no method that can determine exactly when the first day of pregnancy begins. All methods of calculating gestational age are estimates / estimates.
The most commonly used method is to calculate the gestational age starting from the first day of the last menstrual period (HPHT). This method is easy to use if the menstrual cycle is regular. For example the last menstruation occurred on September 15-21. Then the HPHT is 15 September.
HPHT is considered as an estimate of the beginning of pregnancy, despite the fact that pregnancy may occur 2 weeks after HPHT. That's why all gestational ages are estimates. You can consult your obstetrician to confirm the gestational age. Doctors generally match estimates from HPHT and estimates from USG.
Thus my explanation may be useful. Regards.
