The use of progesterone is controversial. It might relax smooth muscles, including the muscles of the uterus.

When to Contact a Medical Professional
If you know you are (or are likely to be) pregnant and you have any symptoms of threatened miscarriage, contact your prenatal health care provider right away.
Women who get prenatal care have better pregnancy outcomes for themselves and their babies. Miscarriages are less likely when you receive early prenatal care. And a healthy pregnancy is more likely when you avoid things that are harmful to your pregnancy such as x-rays, recreational drugs, alcohol, high caffeine intake, and infectious diseases.
It is better to treat health problems before you get pregnant than to wait until you are already pregnant. Miscarriages that are caused by body-wide (systemic) diseases can be prevented by detecting and treating the disease before becoming pregnant. Being obese or having uncontrolled diabetes can increase your risk of miscarriage.
