To estimate the length of your pregnancy, enter the first day of your last period and then press 'calculate'.

This pregnancy calculator gives an estimate of weeks from the reported date of your last menstrual period (LMP). It does not constitute medical advice. We can perform a pregnancy test and do an ultrasound to confirm the length of your pregnancy. Our fees will be based on the results of that determination, which could match your LMP dates but may not.
