Bleeding After Sex: What It Means and When To See a Doctor

Here’s a question nobody ever wants to have to ask: Why am I bleeding after sex?

Vaginal bleeding or spotting following sex is known as postcoital bleeding. Most of the time, it’s nothing serious. But it can sometimes signal larger issues, especially if it’s happening consistently.

Ob/Gyn Christine Oak, MD, explains some of the common reasons why you may be bleeding after sex and when treatment is necessary.

What causes bleeding after sex?

Light spotting after sex is often harmless, but it can sometimes be a symptom of a health condition. And in some cases, Dr. Oak says that those conditions can be contagious.

Common causes

Two of the most common causes of bleeding after sex are also the least threatening: You may be dealing with menstrual blood or experiencing vaginal dryness.

Menstruation

This may seem obvious, but before you call a doctor, consider whether you’re bleeding after sex because it’s that time of the month.

“If you have sex right before or after your period, that may explain your bleeding,” notes Dr. Oak.

Keeping track of your cycle with a menstrual calendar can help resolve concerns and questions like these.

Vaginal dryness

Vaginal dryness is extremely common. It can make having sex painful and, yes, can cause postcoital bleeding. Causes of dryness include:

• Hormonal changes
• Perimenopause or menopause
• Medications
• Autoimmune disorders
• Lack of sexual arousal
• Ovary removal (oophorectomy)
• Irritation from harsh cleansers, menstrual products and more
• Stress and mental health conditions like depression
• Dehydration

“If the dryness is severe enough, the friction can cause bleeding after intercourse,” explains Dr. Oak. “Going forward, using lubrication before or during sex may help. But your doctor might also recommend hormone replacement therapy, if lubricants aren’t sufficient.”

Potential medical causes

Having your period and experiencing vaginal dryness are pretty run-of-the-mill events — so, is it normal to bleed after sex? Not necessarily.

While spotting or bleeding after sex doesn’t have to be cause for alarm, it does need to be checked to rule out pregnancy or an underlying medical issue. Vaginal bleeding may point to:

Pregnancy

Very light bleeding or spotting can sometimes happen if a fertilized egg implants itself along the lining of your uterus. Known as implantation bleeding, this is one of the first signs that you may be pregnant.

If you notice bleeding after sex and your period is late, Dr. Oak advises taking a pregnancy test.

Cervicitis

Cervicitis is inflammation of the cervix, often caused by infections or irritation. Symptoms may include bleeding or a change in vaginal discharge. Possible causes include:

• Sexually transmitted infections (STIs), like chlamydia, gonorrhea or trichomoniasis
• Bacterial vaginosis, an imbalance between the naturally occurring bacteria in your vagina
• Chemical irritation from spermicides, douches or latex in condoms

The bacterial and viral infections that cause cervicitis are contagious, so don’t have sex until you’ve been treated with antibiotics or antifungals and cleared by your provider.

Cervical ectropion

With cervical ectropion, the cells inside your cervix are visible outside of your cervix. This condition doesn’t usually require treatment. But if you have symptoms like excessive discharge or bleeding, Dr. Oak says it could require outpatient heat or cold therapy.

Cervical polyps

Cervical polyps are growths on the opening of your cervix that are sometimes the result of chronic inflammation or hormonal changes. Almost all cervical polyps are benign, and if your symptoms are minor, you may not need treatment.

But sometimes, irregular bleeding can cause abnormal cells to develop. In this case, your polyps will be removed and sent for testing. You may also need to have polyps removed if you experience frequent spotting or cramping.

Uterine prolapse

Uterine prolapse is when your uterus comes out of its normal position. While rare in younger women, this condition occurs more often after a hysterectomy, and it tends to develop slowly over time.

For a minor prolapse, your doctor may recommend weight loss or Kegel exercises to strengthen your uterine muscles. If your condition is severe, your provider can insert a ring to support the tissue or perform surgery to repair it.

Cervical cancer

About 11% of women who have cervical cancer have postcoital bleeding, Dr. Oak reports. In fact, it’s often the first symptom of cervical cancer and may be one of the things you’re most worried about. But don’t assume you have cancer without a definitive diagnosis.

“Most people with postcoital bleeding don’t have cervical cancer,” Dr. Oak clarifies.

She explains that this type of cancer tends to grow very slowly over many years. In most cases, cervical cancer is preventable, as long as you follow up with your gynecologist and have routine Pap and HPV screenings done.

If you are diagnosed with cervical cancer, your doctor will refer you to a gynecologic oncologist for further evaluation.

When to seek medical attention

A good rule of thumb is that any abnormal bleeding, whether it’s just a few drops or a large amount, needs to be evaluated.

“Bleeding that’s not normal for you isn’t necessarily bad. But if it’s happening consistently or you’re getting concerned, get it checked out,” advises Dr. Oak.

How is bleeding after sex diagnosed?

During your visit, your doctor will go over your medical history and ask about:

• Other irregular bleeding
• Heavy or irregular periods
• Unusual pain that doesn’t seem related to the bleeding
• A change in sexual partners
• A change in vaginal discharge
• When you had your last Pap test

They’ll likely do a physical exam to check for signs of infection. You may also get a Pap smear, which can help your provider decide whether you need other screenings or procedures, too.

“Your doctor will outline any necessary testing you may need,” says Dr. Oak. “The important thing to remember is that most of the time, postcoital bleeding is nothing serious.”

Preventive tips

Not all postcoital bleeding can be prevented, but these healthy habits can help keep your sex life safe and enjoyable:

• Get your annual gynecological exam.
• Review the side effects of your medications.
• Manage chronic conditions (with your doctor’s help).
• Stay hydrated for better vaginal moisture.
• Make time for foreplay.
• Use lubricant.
• Wear condoms.
• Avoid harsh cleansers and scented vaginal care products.

Last but definitely not least: Communicate with your partner. If you’re struggling with pain, tightness, tearing or bleeding after sex, you can work together to make intimacy work for you.
