the fluid-filled sac that contains and protects a fetus in the womb

Placenta

aidanserrano — 2025-05-08 17:12:57 UTC

a vital organ that develops in the uterus during pregnancy, facilitating the exchange of nutrients and oxygen between the mother and the developing fetus

Umbilical Cord

a vital structure during pregnancy, serving as the lifeline between the developing fetus and the mother

Fetus (9 weeks)

an offspring of a human or other mammal in the stages of prenatal development that follow the embryo stage

2nd Trimester (14-27 Weeks)

aidanserrano — 2025-05-08 17:16:13 UTC

week 14 to 27, is often considered a smoother period for many women compared to the first trimester

gender is now visible via ultrasound

3rd Trimester (28+ Weeks)

aidanserrano — 2025-05-08 17:19:02 UTC

weeks 28 to 40, is a period of intense fetal growth and preparation for birth.

Braxton Hicks

aidanserrano — 2025-05-08 17:21:14 UTC

sporadic contractions and relaxation of the uterine muscle. Sometimes, they are referred to as prodromal or “false labor" pains

Full Term (39+ weeks)

aidanserrano — 2025-05-08 17:21:51 UTC

A full-term pregnancy is now defined as lasting at least 39 weeks. This means a baby born at 39 weeks or later is considered full-term, and babies born before 39 weeks are considered preterm. This shift from the previous definition of term (37-42 weeks) is based on research showing that babies do best when they remain in the womb for at least 39 weeks.

Labor

aidanserrano — 2025-05-08 17:26:20 UTC

the process of childbirth, starting with uterine contractions and the cervix beginning to thin and open

Delivery

aidanserrano — 2025-05-08 17:26:40 UTC

the process of a baby being born from its mother's womb. It typically involves the stages of labor and the actual delivery of the baby, followed by the delivery of the placenta.

Afterbirth

aidanserrano — 2025-05-08 17:26:50 UTC

The "afterbirth" refers to the placenta, which is expelled from the uterus after the baby is born.
