Ovary pain without a period is usually ovulation pain: a one-sided twinge about two weeks before your next period. Ovarian cysts, endometriosis and infection are other common causes. Sudden, severe one-sided pain, especially with fainting, vomiting or a possible pregnancy, can be an ectopic pregnancy or a twisted ovary. Call 112.
- Mid-cycle pain on one side is most often ovulation pain. It lasts minutes to a day or two.
- Most ovarian cysts cause no symptoms and go away by themselves within a few months.
- If you could be pregnant and have one-sided pain, take a pregnancy test and get checked today.
- Call 112 for sudden severe pain, fainting, shoulder-tip pain, heavy bleeding or trouble breathing.
- Pain that keeps coming back needs a doctor, and often an internal ultrasound scan.

Where is ovary pain felt?
The ovaries sit low in the pelvis, one on each side of the womb. Pain from an ovary is felt low in the tummy, on the left or right, below the belly button. It can spread to the lower back or the top of the thigh.
Many things in that area hurt in a similar spot. The bladder, the bowel and the appendix are close by. So "ovary pain" is a place, not a diagnosis. In Spain a doctor may write dolor pélvico (pelvic pain) or dolor en fosa ilíaca (lower side pain) on your report.
Why do my ovaries hurt when I am not on my period?
Ovulation pain is the most common reason. The NHS describes a dull ache or a sudden sharp twinge on one side of the lower tummy. It comes about two weeks before your period, when an ovary releases an egg. It can last from a few minutes to a day or two. It may switch sides from month to month. Some people notice light spotting or more discharge. Doctors also call it mittelschmerz; in Spanish it is dolor de ovulación.
Other causes the NHS lists for pain like this include:
- Ovarian cysts. Fluid-filled sacs on the ovary.
- Endometriosis. Tissue like the womb lining grows outside the womb. It can cause pelvic pain, painful periods and pain during sex.
- Infection. Sexually transmitted infections such as chlamydia can spread to the womb, tubes and ovaries. This is called pelvic inflammatory disease.
- Scar tissue from past surgery, such as a caesarean section.
- Ectopic pregnancy, when a pregnancy grows outside the womb.
Pain on one side can also come from outside the ovary: a urine infection, constipation, a kidney stone or, on the right, appendicitis.
Is it an ovarian cyst?
Ovarian cysts are common. The NHS says most cause no symptoms and go away within a few months without treatment. Most are "functional" cysts, linked to your normal cycle.
A cyst usually only hurts if it bursts, grows large or twists the ovary. Then you may feel a dull or sharp pelvic pain, pain during sex, bloating, or changes in your bowel or bladder habits.
A cyst is found with an ultrasound scan, usually with a probe inside the vagina (ecografía transvaginal). Cysts are more likely to need checking after the menopause. Then the NHS usually advises repeat scans and blood tests.
When is ovary pain an emergency?
Call 112 or go to urgencias now if pelvic pain comes with any of these. They come from NHS guidance:
- Sudden, sharp, severe pain, or pain that keeps getting worse.
- Feeling very dizzy, faint or passing out.
- Pain in the tip of your shoulder.
- Heavy vaginal bleeding.
- Difficulty breathing or sudden confusion.
Two causes are time-critical:
- Ectopic pregnancy. The NHS says symptoms usually start between weeks 4 and 12. Look for one-sided low tummy pain and odd bleeding, often brown and watery. Shoulder-tip pain can mean internal bleeding.
- A twisted ovary (ovarian torsion). MSD Manuals describes sudden, severe pain, often with nausea and vomiting. Surgery is needed straight away to save the ovary. It is more likely with a cyst, in pregnancy or during fertility treatment. Girls and teenagers can get it with a normal ovary.
Do not drive yourself. In Spain, 112 does the job of 999 in the UK and 911 in the US.
One-sided pelvic pain that keeps coming back, or you are not sure what is causing it?
You can book a video visit with a GP licensed in Spain, in English or Spanish. He goes through your cycle, your symptoms and any warning signs, and tells you which tests or in-person checks you need.
Could ovary pain mean I am pregnant?
Ovary pain is not a reliable sign of pregnancy. But if your period is late, or you have had sex without contraception, take a test. The NHS advises getting checked today if you could be pregnant and have pain on one side, even before a positive test. In Spain, pregnancy tests are sold in pharmacies. Read more in our guide to early pregnancy symptoms.
What helps ovulation pain?
If ovulation is the only cause and the pain is mild, the NHS suggests a warm bath, or paracetamol or ibuprofen. Ask a pharmacist which suits you. If it is bad every month, a doctor may suggest hormonal contraception, such as the pill or an implant, which stops ovulation.
Keeping a diary for two or three cycles helps a lot. Note the day of your cycle, the side and how long it lasts. Pain that always falls mid-cycle and settles quickly fits ovulation. Pain at other times needs a closer look.
When should I see a doctor?
See a doctor today, without waiting, if the pain is severe and painkillers do not help, or you could be pregnant. The NHS also advises urgent advice for pain with a fever or shivers, vomiting, unusual discharge or bleeding, pain when peeing, or blood in your pee or poo.
Book a routine visit if:
- Pelvic pain comes and goes, or does not go away.
- You have pain during sex, or very painful periods.
- You have bloating most days, feel full quickly, or lose weight without trying.
Ovarian cancer is a rare cause of pelvic pain, but these signs should be checked. They usually have a harmless cause.
How Spain differs from the UK and US. In the UK you might call NHS 111 for urgent advice. In Spain you contact your centro de salud or go to urgencias. In the UK and Spain the GP usually arranges the first scan or referral to gynaecology (ginecología). In the US many people go straight to a gynecologist. The warning signs are the same everywhere.
Talking it through with a doctor by video
Dr. Yelamo is a GP licensed in Spain. He sees adults, children and pregnant patients by video, every day from 07:30 to 20:30 (Spain time). In the visit he will:
- Ask where the pain is, when it comes in your cycle and how long it lasts.
- Check for pregnancy, infection and emergency signs, and send you to urgencias if needed.
- Advise on pain relief and tell you if you need an ultrasound, swabs or a gynaecology visit.
He does not promise any test or prescription before the visit. Where clinically appropriate, following a genuine evaluation. Treatment and prescriptions are issued solely at the doctor's discretion based on evidence-based clinical guidelines.
A prescription is never guaranteed: it is issued only where clinically appropriate after a genuine evaluation, as a private electronic prescription under Spanish law. This service is for urgent, non-emergency care. In an emergency, call 112.
See how the Urgent Care video visit works. It lasts 15 minutes and costs €50.

Frequently asked questions
Why do my ovaries hurt when I am not on my period?
The most common reason is ovulation pain, about two weeks before your next period. Ovarian cysts, endometriosis, pelvic infection and, if you could be pregnant, an ectopic pregnancy are other causes.
How long does ovulation pain last?
From a few minutes to a day or two, says the NHS. It is usually on one side and can switch sides from month to month.
Can an ovarian cyst burst?
Yes. A cyst that bursts or twists the ovary can cause sudden, severe pelvic pain, often with nausea or vomiting. That needs emergency care: call 112.
Is ovary pain a sign of pregnancy?
Not reliably. But one-sided pain with a late period or a positive test needs a check today, because it can be an ectopic pregnancy.
When should I go to the emergency department for ovary pain?
Go to urgencias or call 112 for sudden severe pain, fainting or dizziness, shoulder-tip pain, heavy bleeding, trouble breathing, or pain that keeps getting worse.
Which painkiller helps ovary pain?
For mild ovulation pain the NHS mentions paracetamol or ibuprofen and a warm bath. Ask a pharmacist which suits you, and see a doctor if painkillers do not help.
