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

Early in pregnancy, without a sonogram, pregnancy dating is counted from the first day of your last period. Hey Jane uses the first day of your last menstrual period to determine how far along you are in weeks and days. This is called your gestational age. Your fetal age, which is calculated from the date of conception, may be different. 

Your gestational age is how we’re able to determine your eligibility for care. We provide care to patients up to 10 weeks of pregnancy. Beyond that, in-clinic care is likely a better fit.
