Some evidence does support the idea that stress could affect a pregnancy. But the evidence is mixed, and many doctors and health authorities say that stress is not a contributing factor for miscarriage.
How Stress May Affect Pregnancy
Research shows that stress during pregnancy can increase the risk for adverse pregnancy outcomes, including maternal health complications and prematurity. In addition, some studies have found a possible connection between stress and early pregnancy loss. A 2017 systematic review and meta-analysis found that stress before and during pregnancy was associated with pregnancy loss. The results of the study indicate that while chromosomal abnormalities are the predominant cause of miscarriage, psychological stress can increase the risk of miscarriage by as much as 42%. Researchers hypothesize that the connection of stress to miscarriage could have to do with the hormonal implications of stress on the body. For instance, increased cortisol affects the placenta and it impacts how other hormones behave. Prolactin, for example, which stimulates the production of progesterone, is decreased by stress, which means both hormones may be suppressed by stress.
Expert Consensus
Meanwhile, a 2014 systematic review study looking at cortisol levels and in vitro fertilization outcomes, including miscarriage, showed mixed results. Four studies found that lower cortisol was associated with the establishment of clinical pregnancy, while three studies found a correlation between higher cortisol levels and pregnancy. Importantly, major medical organizations and health authorities, including the American College of Obstetricians and Gynecologists (AGOC), the Centers for Disease Control and Prevention (CDC), and the World Health Organization (WHO), do not consider stress a risk factor for miscarriage.
Manage Stress During Pregnancy
It is unlikely that normal everyday stress, such as worrying about your finances or deadlines at work, would lead to a miscarriage, but stress during pregnancy may affect your pregnancy in other ways. So it’s always a good idea to make stress management a priority in your life. Stress may be unavoidable for many people, especially if you’re dealing with something like infertility or recurrent miscarriages. But it’s a good idea to do whatever you can to alleviate anxiety. In doing so, you’ll improve your overall health. Simply put, there is no downside to incorporating more relaxation and stress management into your life. To proactively manage the stress in your life, you might try to:

A Word From Verywell
Sometimes people look back and conclude that they had a miscarriage because they were too stressed out. This can sometimes lead to self-blame, especially in unexplained miscarriages. If you have experienced a pregnancy loss, remember that you didn’t do anything wrong. The causes of most miscarriages are not known. Thinking about reducing stress can sometimes cause people to worry about worrying. Take heart and know that every pregnant person worries at least a little bit during the pregnancy, whether it’s about the pregnancy or about other life factors. Some worry a lot. And yet the majority of people give birth to healthy babies.
