Why Does Domestic Violence Increase During Pregnancy?

Pregnancy is supposed to be a time of anticipation. For some women, it becomes the most dangerous period of their relationship. Research consistently shows that intimate partner violence often begins or intensifies during pregnancy, and pregnancy is recognized as a risk factor for both the start of abuse and its escalation. The reasons are not mysterious. They involve power, control, and a partner’s reaction to a change he cannot control.

Understanding why this happens matters because the pattern is not random. It follows recognizable triggers. Knowing them can help women, families, and clinicians recognize danger earlier.

Why Does Domestic Violence Increase During Pregnancy?

Pregnancy shifts the balance of power in a relationship, and abusive partners often respond to that shift with more control, not less. Several forces converge at once.

The first is loss of control. An abusive partner built the relationship around controlling the woman’s time, body, money, and choices. Pregnancy introduces changes he cannot direct: her body changes, her attention turns inward, medical appointments multiply, and a baby will demand her focus. Abusers often respond to any threat to control with escalation.

The second is the pregnancy itself as a lever. A pregnant woman is more physically vulnerable and often more financially and emotionally dependent. An abusive partner may recognize that she is less able to leave and act on that recognition.

The third is ambivalence about the pregnancy. Some abusers resent the pregnancy, the fetus, or the loss of the woman’s exclusive attention. Others use the pregnancy as a tool, pressuring her about whether to continue it or using it to bind her to the relationship. Research on intimate partner violence during pregnancy points to unintended pregnancy as one factor associated with higher risk, though the relationship is complex and runs in both directions.

The fourth is a documented pattern of first-time abuse. For some women, the first violent incident in the relationship happens during pregnancy. A partner who was controlling but not physically violent may cross that line when the pregnancy changes what he thinks he can get away with.

None of this is caused by the woman’s behavior. The common thread is the abuser’s need for control, and pregnancy is a moment when control feels threatened.

How Common Is Domestic Violence During Pregnancy?

Estimates vary widely because abuse is underreported and studies use different methods. But the pattern across research is consistent: a meaningful share of pregnant women experience intimate partner violence, and pregnancy does not protect against it.

Population surveys and clinical studies have found rates ranging from a few percent to well over 20 percent depending on the population and how abuse is measured. Studies that screen specifically for abuse during prenatal care tend to find higher rates than studies relying on spontaneous disclosure. That gap tells you something important: many women do not volunteer that they are being abused unless someone asks directly and privately.

Violence during pregnancy is associated with serious outcomes for both mother and baby, including miscarriage, low birth weight, preterm birth, and maternal injury. These associations are well established in the medical literature. The relationship is not always causal in a simple way, since abuse often coexists with stress, poor nutrition, delayed prenatal care, and other harms, but the pattern is clear enough that major medical and public health bodies treat pregnancy as a period requiring routine screening for partner violence.

If you are pregnant and being hurt, you are not alone, and you are not to blame.

What Are the Warning Signs That Abuse Is Escalating?

Escalation rarely happens without warning. Abusers often test limits before they cross them, and the signs can be easy to dismiss one at a time.

• Controlling behavior intensifies: monitoring her phone, money, appointments, or contact with family and friends.
• He shows hostility toward the pregnancy, the baby, or the attention she receives.
• He pressures her about the pregnancy, including demands about continuing or ending it, or about how she manages her health care.
• He isolates her from prenatal appointments or insists on attending every one to control what she says to clinicians.
• Arguments escalate faster, or threats, shoving, or grabbing appear for the first time.
• He blames the pregnancy for his temper or says she has changed.

Any one of these is a reason to take the situation seriously. A pattern of several is a strong signal. The most dangerous period in an abusive relationship is often when a woman tries to leave or when the abuser believes he is losing control, so planning safety matters more than acting on impulse.

Why Do Some Women Stay, and Why Leaving Is So Hard?

Leaving an abusive relationship is one of the most dangerous things a woman can do, and pregnancy makes it harder. This is not a failure of will. It is a calculation shaped by real risks.

Pregnancy brings physical vulnerability, financial dependence, and often a deeper emotional tie to the partner. Many women hope the baby will change him. Some fear losing the baby, or fear what he will do if she tries to leave while pregnant. Others have no safe place to go, no money of their own, or family and community pressure to keep the relationship together.

Abusers actively work to make leaving harder. They isolate, threaten, control money, and sometimes threaten to take the child or report her to authorities. The result is a trap that looks, from the outside, like indecision.

The evidence on leaving is worth stating honestly: safety planning with a trained advocate is associated with better outcomes, and leaving is not always immediately safer. The goal is not simply to leave. It is to leave safely, with support. Anyone helping a pregnant woman in this situation should focus on her safety and her choices, not on convincing her to act on someone else’s timeline.

What Should You Do If You Are Being Abused During Pregnancy?

Your safety comes first, and there are concrete steps that can help.

Tell someone you trust, and tell a clinician if you can. Prenatal visits are a private setting where many women first disclose abuse, and clinicians are trained to connect women with resources. If your partner monitors your appointments, look for a moment alone with a nurse or doctor, or call a hotline from a safe phone.

In the United States, the National Domestic Violence Hotline is available 24 hours a day. The number is 1-800-799-7233. You can also reach the hotline by text or online chat. These services can help you make a safety plan and find local shelters and advocates.

A safety plan does not require leaving. It can include:

• Keeping important documents, money, and a phone where you can reach them quickly.
• Identifying a safe place to go and a person you can call.
• Agreeing on a code word with a trusted person so they know to call for help.
• Knowing the fastest route out of your home and where the nearest hospital is.
• Telling your prenatal care team so they can support you and document injuries if needed.

If you are in immediate danger, call 911. Do not wait to see whether things calm down.

What Can Friends and Family Do to Help?

If you suspect a pregnant woman you know is being abused, the most useful thing you can do is make it easier for her to talk, not harder.

Ask directly and privately, without judgment. Say something like, “I am worried about you. Is someone hurting you?” Believe what she tells you. Do not pressure her to leave on your timetable, and do not confront the abuser. Confrontation can increase danger.

Offer practical help: a place to stay, a ride to appointments, childcare, money, or simply a phone she can use. Stay in contact. Isolation is one of the abuser’s main tools, and consistent connection is one of the strongest counterweights.

Know the resources. The National Domestic Violence Hotline can advise friends and family as well as victims. Local domestic violence agencies often provide shelter, legal advocacy, and safety planning.

Pregnancy does not cause domestic violence, and it does not protect against it. It is a period of heightened risk because it changes the balance of power, and abusers respond to that change with more control. Recognizing the pattern is the first step toward safety, for the woman and for the baby she is carrying.
