About this tool
Enter the first day of your last menstrual period. The calculator shows how many weeks and days pregnant you are, the trimester, the expected due date (280 days from that date) and the days left. It is an estimate; an ultrasound can adjust the dates.
How pregnancy weeks are counted
Pregnancy is counted from the first day of the last menstrual period, so you are about two weeks pregnant at conception. A full term is about 40 weeks, or 280 days.
Trimesters
The first trimester ends at week 13, the second at week 27 and the third runs to birth.
Please note
