Pregnancy Calculator
Enter the first day of your last period
The pregnancy calculator below is only an estimate of weeks pregnant. This calculation does not constitute medical advice. Missing a period does not necessarily mean that you are pregnant. Having a period does not mean you are not pregnant. Only an exam, pregnancy test, or ultrasound by a physician can confirm pregnancy and approximate length of pregnancy. This calculator is only a guide. To estimate the length of your pregnancy, enter the first day of your last period and then press ‘Submit’.
