Trimester Chart

It was always hard to figure out what week belonged to what month and what month belonged to what trimester while I was pregnant. I found this out because there are two ways to calculate how many weeks you are:
  1. Your pregnancy starts the last day of your last full period. This is what most doctors will follow (this one is the common one).
  2. Your pregnancy starts from when you missed your period. This does not include the conception timeframe. Therefore, the first month of pregnancy would start at 5 weeks. 

We will be using the 1st method to determine Month/Week on this website to help things stay consistent.
