How many weeks pregnant are you? Enter the date of the first day of your last menstrual period (LMP) and we'll calculate a week-by-week timeline for you.

Most healthcare practitioners calculate the age of your pregnancy by the number of weeks since your last period (menstrual age). If you want to know the gestational age of your fetus, simply enter the date of conception (or, as an estimate, 14 days before your period was due). Note: Your browser must be Java-enabled for the calculator to work.

I am 9 days late. I took a pregnancy test early this morning and it turned out negative. Where is my period? Should I consult a doctor already? :(

It takes sometimes time for you to generate the pregnancy hormone - if you tested that many times and still negative see a doctor to confirm - they use a blood test which is more accurate

I was two days late, very tired, and felt a little queasy, so I took a pregnancy test, and it was positive! I took 2 more that same day (First Response), then a fourth that night (Clearblue Easy). All positive! Going to OB in two weeks!
