The primary female hormone injection used during pregnancy, particularly to prevent preterm labor, is 17P, which contains progesterone.
17P Injections and Progesterone
- Hormone: Progesterone
- Purpose: Helps prevent contractions of the uterus. The uterus contracts during labor to help push the baby out.
- Timing: Doctors typically recommend starting 17P shots during the second trimester of pregnancy (usually between 16 and 20 weeks).
- Duration: Injections are generally continued until 36 weeks of pregnancy.
