The first 3 months of pregnancy.
The period of time when a fetus is developing in the womb.
The length of a pregnancy. Measured from the first day of the last menstrual period.
When a pre-embryo attaches to the lining of the uterus. This is when pregnancy begins. Usually starts about 6 days after fertilization (when egg and sperm meet) and takes 3 to 4 days to complete.
A procedure done in a health center, doctor’s office, or hospital that ends a pregnancy.
A kind of miscarriage or abortion in which some pregnancy tissue passes out of the uterus but some stays inside. Sometimes treatment is needed to remove the remaining tissue.
The intentional termination of pregnancy.
Miscarriage that’s medically certain to happen in the near future.
A procedure that allows a minor to receive court approval for an abortion without her parents’ knowledge or consent. Some states require judges to use specific criteria when determining whether to grant a waiver of parental involvement.
Manual vacuum aspiration (MVA)

When an embryo or fetus dies before the 20th week of pregnancy.
A medication that can be used to complete a medication abortion that’s been induced with mifepristone. This process is commonly known as the abortion pill. Although less effective than mifepristone, misoprostol is used alone for abortion in some countries.
Missed abortion / missed miscarriage
When a pregnancy ends, but the tissue remains in the uterus. Sometimes this can lead to a person continuing to experience pregnancy symptoms for a time. Treatment is sometimes needed to remove the tissue from the uterus.
Emergency contraception that can be used within 120 hours (5 days) of unprotected vaginal sex to decrease the chance of pregnancy.

When someone is carrying a developing fetus in their uterus. It begins with the implantation of the pre-embryo and progresses through the embryonic and fetal stages until birth, unless it’s ended by miscarriage or abortion. It lasts about 40 weeks from implantation to birth.
Supporting the right to a safe, legal abortion.
The presence of certain proteins on the surface of red blood cells. People with Rh factor are “Rh positive,” and people without it are “Rh negative.” Commonly known as a positive or negative blood type. Pregnant people and their fetuses may be tested for Rh factor, because if the pregnant person is negative and the fetus is positive, it can be dangerous.
