THIS IS HOW TO DETERMINE THE LENGTH OF YOUR PREGNANCY BASED ON THE DATE OF ONSET (FIRST DAY) OF YOUR LAST MENSTRUAL PERIOD (LMP)
Since it is difficult to pinpoint the exact moment at which a woman ovulated and conceived, health professionals conventionally refer to the length of pregnancy as the time that has passed since the first day of the last menstrual period (LMP).
If a woman wants to know how far along her pregnancy is since the time that she conceived (which technically is known as the gestational age) she will need to subtract two weeks from the total weeks of pregnancy that was calculated above. The reasons are as follows: gestational age is counted from the day of conception; conception takes place within 12 hours after ovulation; and ovulation usually occurs in the middle of the menstrual cycle, which is about two weeks after the first day of the menstrual period.
Determinations of length of pregnancy and gestational age that are based on the date of the last menstrual period are only an estimate that should not be considered a diagnosis and are not a substitute for an ultrasound examination.
Due to false menstrual periods that may occur during an otherwise normal pregnancy or bleeding that sometimes occurs with ovulation, an estimate that is based on LMP may be incorrect even when the woman is certain of the date of her last menstrual period.
The most accurate method to determine the length of a pregnancy is by ultrasound examination. The accuracy of the ultrasound is better when obtained early in the pregnancy.
