My doctor keep asking me "What is your last menstrual period (LMP)?", what is it actually means?

"LMP" is short for "Last Menstrual Period." This is the first day of your most recent menstrual cycle and is a term commonly used in healthcare, especially in the context of pregnancy and gynecological health.

Here's a simple way to explain it:

Your LMP, or Last Menstrual Period, is basically the starting point for calculating the timeline of your pregnancy or your menstrual cycle. Think of it like the first page in a new chapter of a book. On this day, your body starts a new menstrual cycle. The day your period starts is considered day one of this cycle.

In terms of pregnancy, the LMP is important because it gives doctors a standardized point from which to measure the age of a fetus, estimate your due date if you're pregnant, or even track fertility. This might seem strange because conception usually happens about two weeks after the LMP, but it's just the way it's traditionally been done in the medical community. 

So, when a doctor asks for the date of your LMP, they are asking when the first day of your last period was. It's always a good idea to track your menstrual cycle, not just for pregnancy-related reasons such as couples planning to get pregnant, or avoiding pregnancy but also for your overall reproductive health. There are many apps and tools available nowadays that can help you do this.

Remember, your LMP is just one part of understanding your menstrual cycle and reproductive health. If you have any questions or concerns, you should consult with your healthcare provider.
