• Among women who are not planning to get pregnant, the progesterone level ranges from 0.2 – 1 ng/ml before ovulation and over 5 ng/ml after ovulation.
• During the luteal phase, the level of progesterone increases and may even exceed 200 ng/ml if pregnancy does occur.
• For pregnant women, a high level of progesterone in the blood is necessary until the baby is born. In fact, pregnant women who lack progesterone are prescribed supplements to avoid the possibility of a miscarriage.

Progesterone's role in pregnancy

Progesterone, an important hormone during pregnancy, is essential for preparing the uterus for implantation, sustaining a safe pregnancy, and preparing the body for during lactation. It thickens the uterine lining, reduces uterine contractions, and helps to prevent preterm labor. Here's a thorough breakdown of the role Progesterone plays during a pregnancy:

Preparing the Uterus for implantation: Progesterone thickens the uterine lining (endometrium), providing a favorable environment for a fertilized egg to implant. It promotes the development of blood vessels and glands in the endometrium, which release nutrients to sustain the embryo.

Maintaining a Healthy Pregnancy: Progesterone prevents uterine contractions, which can lead to premature labor or miscarriage. It assists in the growth of the fetus by creating a stable and supportive environment within the uterus. 
Preparing for Breastfeeding: Progesterone stimulates breast tissue growth, preparing the mammary glands for lactation.

How does low progesterone affect pregnancy?

Low progesterone levels during pregnancy can result in the following:

Uterine Lining: Progesterone plays a critical role in maintaining a healthy and thick uterine lining (endometrium), which is essential for successful pregnancy development and egg implantation. Low progesterone may interfere with these.

Implantation: Low progesterone levels might hinder the body's capacity to form a healthy uterine lining, making it challenging for fertilized eggs to attach and implant.

Pregnancy Maintenance: To maintain a pregnancy, strong progesterone levels are necessary to sustain the embryo and avoid contractions that could cause miscarriage or preterm labor.

Risk of Miscarriage: Low progesterone levels might increase the chance of miscarriage, especially during early pregnancy. 

Other Complications: Low progesterone levels can lead to many pregnancy issues, including miscarriage, preterm labor, and ectopic pregnancy.

Infertility: In some situations, low progesterone levels can make it difficult to get pregnant in the first place, as the body may be unable to maintain the uterine changes required for implantation.

Luteal Phase Defect: Low progesterone levels during the luteal phase of the menstrual cycle might make it difficult to conceive and maintain a pregnancy.

When to See Doctors?

Spotting or Bleeding During Pregnancy: If you experience spotting or bleeding during your pregnancy, get quick medical assistance since it may indicate difficulties.
