If you do not know exactly how many weeks pregnant you are, you are not alone, and your clinical team can help you figure it out safely. Many people have irregular periods, fluctuating cycles, or trouble remembering the exact date of their last menstrual period.
How Clinicians Determine Pregnancy Dating
Date of Last Menstrual Period (LMP)
Your provider will start by asking for the first day of your last normal period. Even if your cycles are irregular or you only have a general timeframe, this gives your care team a vital baseline. To learn more about how clinical screenings are structured, read our guide on expert answers on abortion.
Ultrasound Imaging
If your LMP is uncertain, irregular, or falls near the limit for medication abortion, your clinician may recommend an ultrasound. An ultrasound provides an accurate measurement of the pregnancy to confirm gestational age and ensure the pregnancy is located inside the uterus. To understand how safe remote care workflows manage these evaluations, review our overview on how does a virtual abortion work.
Blood Tests (hCG Levels)
In some situations, serial blood tests to check pregnancy hormone (hCG) levels over a few days can help providers understand how a very early pregnancy is progressing.
Why Knowing Your Gestational Age Matters
-
Treatment Options: Medication abortion (abortion pills) is generally effective and approved up to a certain point in pregnancy (typically up to 10 to 11 weeks). If a pregnancy is further along, an in-clinic procedure may be recommended.
-
Safety and Effectiveness: Accurate dating ensures you receive the correct medication dosage and appropriate clinical oversight. To explore recovery guidelines after treatment, read our resource on how to heal after an abortion.
