Related FAQs

Why is the state pregnancy stage limit different from the health center pregnancy stage limit?

One type of state law that could affect your abortion has to do with how far along in pregnancy abortion is allowed in your state. (How far along you are in pregnancy is calculated based on the first day of your last period. We’ll figure it out for you—[just give us the first day of your last period.](/)) For example, some states might allow abortions through 14 weeks and 6 days of pregnancy. Other states might allow them through 20 weeks and 6 days of pregnancy. Still others don’t have any specific limits on how far along in pregnancy you can get an abortion. Some states ban abortion completely. In addition to these state limits, individual abortion providers decide how far into pregnancy they want to offer abortion, so just because your state doesn’t ban abortion until 22 weeks doesn’t mean every abortion provider will offer abortions through 22 weeks. It’s legal for you to travel to another state to get an abortion, so if providers aren’t available in your state or if you’re past your state’s pregnancy stage limit, we’ll help you figure out where it will be possible for you to get an abortion.

Why do we ask you for the first day of your last period?

How far along you are in pregnancy is calculated based on the first day of your last period. How far along you are affects a lot about abortion, including what types of abortion are available to you. Also some states don’t allow abortion past a certain point in pregnancy. If you give us the first day of your last period, we’ll calculate how far along you are and provide you with additional information to help you navigate selecting an abortion provider. We’ll also show you a list of results for providers that offer abortion services at your pregnancy stage.

Why do we ask you for your age?

There are laws in many states that require people younger than 18 to involve a parent or guardian before they can get an abortion. We ask for your age so we can let you know if any of these laws will affect you. We will never share your personal information.
