How Far Along Am I?
Understanding your pregnancy timeline and gestational age
Pregnancy dating is calculated from the first day of your last menstrual period (LMP), not from the day you had sex or conceived. This is the standard medical method used by healthcare providers worldwide.
For example, if the first day of your last period was January 1st, you would be considered 4 weeks pregnant on January 29th, even though conception likely occurred around January 15th.
Most people don't know exactly when conception occurred, but they usually remember when their last period started. This makes it a reliable reference point for calculating pregnancy.
Ovulation and conception typically occur about 2 weeks after the start of your last period. This means that in the first 2 weeks of "pregnancy" by medical calculation, you aren't actually pregnant yet—it's just the way the timeline is measured.
If you have irregular periods or can't remember when your last period started, estimating gestational age can be more challenging. In these cases:
- Think about when you last had unprotected sex
- Consider any symptoms you've noticed and when they started
- An ultrasound (if available) can provide more accurate dating
- Our providers can help you estimate your timeline during consultation
Medication Abortion Timeline
Medication abortion (the abortion pill) is typically available up to 11 weeks (77 days) from the first day of your last period. The earlier in pregnancy you take the pills, the more effective they are.
