I don’t remember well which week of pregnancy I’m in. I don’t know how other women answer immediately when asked. I need to use the due date calculator each time. This is for today:

Today is Monday July 18th 2011.
You conceived on Monday February 28th 2011
and your due date is Monday November 21st 2011.

140 days have passed since the conception,
and you are 126 days before your due date.

You are 22 weeks into your pregnancy,
and you have 18 weeks to go.

You are in the 2nd trimester.

53% of your pregnancy has passed, there is 47% left to go.
