It is said that pregnancy lasts for ten months, and many people know that delivery will take place around 40 weeks after conception. However, many pregnant women often do not know the specific date of conception, so it is difficult to calculate some pregnancy related dates, such as the number of days of pregnancy and the expected delivery date. Next, let's take a look at what to do if you don't know when to get pregnant?
I don't know when I'll get pregnant. What should I do
In fact, the number of days of pregnancy is usually calculated from the last day of the last menstrual period, so as long as you know the last day of the last menstrual period, you can calculate the number of days of pregnancy and the due date. The calculation method for the due date is menstrual plus 9 or minus 3, and the date plus seven days. For situations where the date of the last menstrual period cannot be provided, the estimated time of pregnancy and due date can only be inferred based on the ultrasound results.
How to Calculate Pregnancy Days
The first step is to calculate the correct number of days of pregnancy, starting from the first day of the last menstrual period, rather than from the day of intercourse. Many people start calculating the number of days of pregnancy from the day when sperm and egg combine, but this algorithm is actually incorrect.
Another thing is the number of days we have been pregnant since the first day of our last menstrual cycle until now. It's actually quite easy to calculate, because it's possible to conceive before or after the last menstrual period, and some people may even have a baby before their last menstrual period.
Another method is to calculate the actual conception time by subtracting fifteen days from the number of days obtained by the previous calculation method. Because this time is around the actual ovulation period, but this algorithm is limited to women with regular menstrual cycles.
So, generally pregnant women do not need to determine the exact day of pregnancy to determine the specific number of days of pregnancy. As for the calculation of pregnancy days or due date, as long as the last day of the last menstrual period is known, it can be calculated. Of course, if you don't even know your last menstrual period, you can only rely on the ultrasound results to ask the doctor for help in guessing.
