How is Pregnancy Due Date Calculated?
Following are the methods to estimate pregnancy due date:
First Day of Last Period
The first day of your last menstrual period (LMP) is the most common method to estimate your pregnancy due date. Most of the pregnancy due date calculators are designed accordingly. Usually pregnancies last around 40 weeks (or sometimes 38 weeks) from the date of conception. This is the method that most of the doctors use to estimate the due date and count 40 weeks or 280 days to the first day of your last period.
Another common method is to subtract three months from the last period’s date and add seven days to the date. Understanding it by an example would be best. Suppose you had the last period date on 12th May, subtracting three months from this date will lead to 12th February and adding 7 days to it result in 19th February, that is your estimated due date.
The above mentioned LMP method may not work well for every woman. Because it is appropriate for the women who have regular menstrual cycles. But for the ones having irregular menstrual cycles, the pregnancy due date can’t be accurately estimated with that method. For this purpose, conception date method is the suitable one.
If you remember your conception date, your consultant can easily calculate the estimated due date (EDD) by adding 266 days to it.
IVF Transfer Date
IVF transfer is the widely used technology for getting conceived. Known as In Vetro Fertilization (IVF), this procedure aids with fertility issues (as well as prevent genetic problems) and help out in conceiving a baby. In this complex procedure, mature egg are extracted from ovaries and fertilized by a sperm in the laboratory. Then, these fertilized eggs (called embryos) are transferred to a uterus.
