How does Hey Jane determine how many weeks pregnant I am, and why is it important?

If you have regular periods, Hey Jane can typically calculate how far along your pregnancy is based on your last menstrual period (LMP). Counting from the first day of your last period, we can usually determine your estimated gestational age (EGA), which is how far along the pregnancy is in weeks and days. This method is very reliable for most people, and additional testing usually isn’t required to date a pregnancy unless you have a history of irregular periods and are not able to confidently date the pregnancy using other methods.

Hey Jane provides medication abortion care for patients up to 10 weeks of pregnancy, which is why accurately estimating the gestational age of the pregnancy is important. Beyond that, in-clinic care is likely a better fit.
