When it comes to pregnancy, many expectant parents find themselves asking how long it actually lasts. It’s essential to know the breakdown of weeks, months, and trimesters to help you navigate this exciting journey.

How Many Weeks in a Pregnancy?

A typical pregnancy lasts about 40 weeks, starting from the first day of your last menstrual period (LMP). This duration is divided into three trimesters, each with its own unique developments.

How Many Trimesters Are There?

Pregnancy is divided into three trimesters:

  • First Trimester: Weeks 1-12
  • Second Trimester: Weeks 13-26
  • Third Trimester: Weeks 27-40

Months vs. Weeks

While pregnancy is often said to last nine months, this can be a bit misleading. The 40 weeks translate to about 9.2 months, making it a full-term pregnancy slightly longer than the traditional nine-month framework.

Calculating Your Due Date

Determining your due date can be tricky, but it’s typically calculated based on your last period. For a more tailored approach, tools like the At Home Insemination Kit can guide you through this process.
