Why Last menstrual period (LMP) date is important in pregnancy?

 Let’s start with date of first day of menstrual cycle. This date of first day of menstrual cycle is very important while calculating duration of pregnancy. Whenever you go to doctor, he will ask for this date. Your healthcare provider will also ask the date of start of last menstrual period. As it is difficult to know, when exactly conception occurs so we calculate due date from the beginning of last menstrual period. And this method of calculating duration of pregnancy with is widely used all over the world. It is easy and more reliable to calculate duration of pregnancy with LMP.

FIRST WEEK OF PREGNANCY

During first week of menstrual cycle you are having your periods. So nothing special happening during this week.

SECOND WEEK OF PREGNANCY

 During second week your egg is making itself ready for its release from ovary. The ovulation occurs around 14th day of menstruation and conception will occur after ovulation (assuming duration of your cycle  is 28 days).

Another thing is happening inside you is development of endometrium as it always occur during each second week of pregnancy.

THIRD WEEK OF PREGNANCY

As soon as egg releases it enters into fallopian tube and starts travelling towards uterus. If you had sex during these days and sperms are available in fallopian tube, FERTILIZATION may occur.   You will be pregnant in around third week of your menstrual cycle.

Do you know, as soon as the lucky sperm enters the egg, it develops changes in its wall, so no other sperm can enter the egg now. There is no chance for any other sperm now. Yes it is sad for rest of sperms who lost race but its law of nature, only one wins.

When sperm enters egg, it becomes zygote. Zygote starts to divide in two, four, eight cells and division of cells continue. this cluster of cells moves towards its destination in uterine wall. It burrows itself in lining of uterine wall. This process of burrowing in uterine wall is called IMPLANTATION.

If you have slight spotting (a lot lighter than periods) , it is due to implantation of zygote.
