When did I get conceive? Calculate the date of conception

When did I actually become pregnant? When attempting to determine the precise day that their pregnancy started, many women frequently ask this question. The age of the baby, or gestational age, is frequently determined starting on the first day of the mother’s last menstrual cycle. The baby was not actually conceived until the egg was fertilized and ovulated, which typically takes place at least 10 days after the first day of the mother’s menstrual cycle.

An exact date of conception is difficult to determine because there are so many variables. This calculator assists in estimating the range of actual conception dates as well as the potential range of days during which sexual activity may have resulted in conception. The following techniques can be used to determine the conception dates:


Menstrual Cycle Before


When a woman has a normal cycle, conception typically happens 11 to 21 days following the start day of the previous period. Based on this, the conception date is estimated, albeit it is never precisely known when ovulation takes place. Women with irregular cycles or those who can’t recall the first day of their last period may find it more challenging to determine the date of conception. An ultrasound is one of the more reliable methods in these situations for determining gestational age.


Expires on


During a prenatal checkup, a healthcare professional will often offer you with an estimated due date, usually based on a sonogram. A variety of potential conception dates can be calculated using this due date.


 Ultrasound for Calculate the date of conception


On the most fundamental level, an ultrasound employs sound waves to produce images of inside body structures. “Obstetric ultrasonography” refers to an ultrasound that is used to monitor the development of the fetus in pregnant women. As it can provide information regarding the health of the mother and embryo/fetus, as well as the general progress and timing of the pregnancy, this is carried out in real-time and is a very standard procedure that is a part of prenatal care in many countries. As early as five or six weeks after the mother’s last period, ultrasounds can be used to measure a fetus. In the early stages of pregnancy, it is a more accurate gauge than it is later on. For a more precise estimation of gestational age, ultrasound can be utilized in conjunction with calculations based on the most recent menstrual cycle.
