After you announce your pregnancy, the first question you'll probably be asked is "When are you due? Keep in mind that only about 30 percent of pregnancies will reach precisely week There are three trimesters in a pregnancy: the first trimester , which lasts from approximately weeks 1 to 13, the second trimester , which lasts from about week 14 to week 27, and the third trimester , which lasts from around week 28 to week 40 and up.
Your 40 weeks of pregnancy are counted as nine months. But wait … there are four weeks in a month, which would make 40 weeks 10 months. Not exactly. Four weeks is 28 days, but months with the exception of February, of course have 30 or 31 days, making each month about 4.
If you're carrying a single baby, a full-term pregnancy is between the start of 39 weeks up to the end of 40 weeks. If you're carrying twins, a full-term pregnancy is considered at least 38 weeks.

The LMP is simply a more reliable day to date a pregnancy from.
