Estimate the Length of the Pregnancy Based on Your Last Menstrual Period (LMP)

Once you have confirmed that you are pregnant, the next step is to explore your options. In order to do that, you need to determine the length of the pregnancy. Most physicians make this determination by measuring from the first day of your last menstrual period (LMP). You may use the calculator below to estimate the length of the pregnancy:
