What Causes Cramps with No Period?

Lots of women get pelvic pain and cramping, but your period isn’t always to blame. Cysts, constipation, pregnancy — even cancer — can make it feel like your monthly visitor is about to stop by.

It can be tough to tell whether having cramps without a period is caused by something simple or more serious. But there are common reasons for cramping without your period.

An inflammatory bowel disease (like Crohn’s disease or ulcerative colitis)

What it is: You get long-term (chronic) swelling and irritation in different parts of your digestive tract. It happens when something goes haywire in your immune system. It isn’t the same as irritable bowel syndrome (IBS). Crohn’s can affect any part of your digestive tract (including your mouth). Ulcerative colitis involves only the large intestine (colon).

What the cramps feel like: It depends on the type of IBD you have. With Crohn’s, you’ll feel cramps and pain in the right lower or middle parts of your belly. They can be mild to severe. If you have ulcerative colitis, the cramps will be on the lower left side of your stomach.

Other symptoms: Which ones you have depend on the specific type of IBD. They include:

  • Severe changes in bowel movements (diarrhea, constipation)
  • Urgent need to pass a bowel movement
  • Feeling that your bowels aren’t completely empty after you go
  • Blood in your poop
  • Weight loss
  • Fever
  • Fatigue


What it is: If you haven’t gone through menopause and still have your ovaries, you might get cramps mid-month, about 10-14 days before your period. This happens when your ovaries release an egg to ready your body for a possible pregnancy. The harmless twinge of discomfort is called “mittelschmerz,” which means middle pain.

What the cramps feel like:You’ll notice pain on one side of your lower belly. It lasts a few minutes to a few hours. It can be sharp and sudden, or you might just have a dull cramp. The side of the pain depends on which ovary released the egg. It may switch sides every month or strike the same place each time.

Other symptoms: There aren’t any.

Ruptured ovarian cyst

What it is: A cyst is a sac of fluid. Sometimes they form on your ovaries. One type, called a follicular cyst, breaks open to release an egg and later dissolves in your body. If this doesn’t happen, a different cyst can form. Most are harmless. But if one grows large, it could burst.

What the cramps feel like: A ruptured cyst doesn’t always cause pain. If it does, you might have sudden, sharp cramps on either side of your lower stomach below the belly button. The location depends on which ovary had the cyst.

Other symptoms: You may also have some spotting. Before the cyst ruptures, you may feel pain or pressure in your lower belly, thighs, or lower back.

Pregnancy pain

What it is: Your growing baby is attaching to the lining of your womb, or uterus. This is called “implantation pain,” and it’s a sign of pregnancy progress.

What the cramps feel like:You might have a few slight cramps about 4 weeks into your pregnancy — around the time when you’d get your period. If you aren’t sure whether you’re pregnant, it’s a good idea to take a test.

Other symptoms: There are none. If you’re pregnant, you might start to feel queasy around the fifth or sixth week.

Ectopic pregnancy

What it is: This is when a baby grows somewhere other than your womb. Most often it happens in one of your two fallopian tubes. It’s life-threatening for the mother and can’t result in a live birth.

What the cramps feel like: You may have mild cramps followed by sudden, sharp, stabbing pains on one side of your lower belly. The pain can get so severe that you also feel it in your shoulder and lower back.

Other symptoms:Before the cramps, you may have had typical pregnancy signs, like nausea and sore breasts. But not all women with an ectopic pregnancy have those. You might not even know you’re pregnant.


What it is: It’s the loss of an unborn baby before the 20th week of pregnancy.

What the cramps feel like:They might start out like period pains, and then get more severe.

Other symptoms: You may have vaginal bleeding or spotting. Some pregnant women have these symptoms but don’t miscarry. But if you’re expecting and either one happens, always call your doctor.


What it is:This is a long-term (chronic) condition in which tissue similar to your womb’s lining attach to other organs and begin to grow.

What the cramps feel like: They seem like regular period cramps, but they can happen any time of month. You may also have cramps and pain in your low back and stomach below your belly button.

Other symptoms: Sex that involves deep penetration may be painful. Some women have painful bowel movements. Endometriosis can make it hard to get pregnant.

Pelvic inflammatory disease (PID)

What it is:It’s a bacterial infection that’s usually spread by sex. It affects the parts that help you conceive and grow a baby. This includes your fallopian tubes, womb, ovaries, vagina, and cervix.

What the cramps feel like: You’ll have pain on both sides of your lower belly and lower back. It can happen any time of the month.

Other symptoms:PID causes abnormal vaginal discharge and, sometimes, spotting. You might have pain or burning during sex or when you pee. Your periods might be heavier or longer. You might run a fever or have nausea and vomiting. You’ll need to get the disease treated by a doctor.

Pelvic-floor muscle dysfunction

What it is: Severe spasms happen in the muscles that support your bladder, womb, vagina, and rectum. It can happen after you have trauma with vaginal childbirth or after an injury, like a car accident.

What the cramps feel like: They’re severe — like sudden leg cramps in your lower belly. You may also have ongoing pain in your groin and back.

Other symptoms:You might have pain during your periods or sex, a burning feeling in the vagina, and problems pushing out stools. It could burn when you pee, or you may have a strong urge to go all the time. If you have these symptoms, see a doctor for a urine test to rule out a bladder infection. If you have one, the doctor will see bacteria in your urine.

Interstitial cystitis

What it is: This long-term condition affects your bladder. Some doctors call it “painful bladder syndrome.”

What the cramps feel like: You’ll notice them in your lower stomach (pelvic) area and in your genitals, along with pain and tenderness. They’ll get worse as your bladder gets full and when it’s almost time for your period.

Other symptoms: You’ll feel like you have to pee a lot, and it’ll be urgent. Sex might also hurt.

Irritable bowel syndrome

What it is: This disorder causes stomach pain and bloating with diarrhea, constipation, or both.

What the cramps feel like: They’re sudden and in your belly. They might go away after you poop. Your specific pain will depend on whether you have constipation or diarrhea. You might go back and forth between the two or only have one type. Symptoms usually get worse during your period.

Other symptoms:You might feel pressure, like you tried to go, but couldn’t fully empty your bowels. You might feel sick to your stomach, have gas, or spot mucus in your poop.

There could be many such reasons.

Always call a doctor if you have cramps that won’t go away, whether or not you have your period. (Get medical help right away if you have sudden, severe belly pain that continues to get worse.)

Your doctor will want to know if your pain is sudden or ongoing. The more details you can give, the faster they may be able to diagnose and treat you. You’ll be asked questions about your symptoms and your periods.

Your doctor may do tests or procedures to learn the cause of your cramps. If your doctor suspects it is related to your uterus, or ovaries, common tests are:

  • Pelvic exam
  • Ultrasound
  • Laparoscopy, a type of exploratory surgery to look at the structures inside your pelvic area, including your uterus, cervix, ovaries, and fallopian tubes. 

Your doctor may refer you to someone who specialize in stomach or intestinal disorders or a urologist if they suspect that cramps are caused by any of those areas .
