Explore your due month
Every pregnancy due in the same month shares a set of date ranges: when the last period was, when conception likely happened, and when each trimester and term window begins.

Why ranges, not single dates
A month contains 28 to 31 possible due dates, so each milestone is a range from the first to the last of them. Ranges for the last period and conception assume a 28-day cycle; your own dates may sit a little outside them.1 For exact dates, use the due date calculator.
We publish month pages a little over a year ahead and add new months as they come into range.
