Vomiting and Nausea During Ovulation: Is It Normal Or Pregnancy Sign?

Question: What causes vomiting and nausea during ovulation?

Menstrual period usually starts in a lot of girls between the ages of 12 and 16. After your first menstrual period, your body hormones adjust, and you notice new symptoms before and during your period.

One new problem after your “first period” is belly pain before and during your menstrual period. In some women, this pain may also occur weeks back when you’re ovulating with the feeling of throwing up.

Nausea can happen anytime in your menstrual cycle and can be discomforting to a lot of women.

After your monthly period ends, your body moves into the time of the cycle when ovulation will happen. During ovulation, which is the cyclical release of an egg from your ovary, some women will get a nausea feeling.

If your menstrual cycle is 28 days, ovulation usually takes place around the middle of your cycle (about day 14), which is roughly 2 weeks before your next period, not exactly one week after your period ends. Cleveland Clinic

Is nausea during ovulation normal?

The truth is, if you get nausea during ovulation, it’s not abnormal, so don’t panic all the time. In many women, it’s due to hormone changes and sometimes to pain during ovulation.

Then again, feeling nauseous may be a sign of pregnancy, especially if you’ve missed your period. Also, if you’ve mistaken light implantation bleeding for your period, you may also get nausea around the same time. Nausea is a common symptom during early pregnancy and part of what doctors call morning sickness (nausea and vomiting of pregnancy). MedlinePlus+1

On the other hand, there are other causes of nausea (apart from ovulation). Stomach flu (gastroenteritis), food poisoning, peptic ulcer, acid reflux, some infections, and many drugs may cause women to have nausea. Good overviews are available on nausea and vomiting and diarrhoea and vomiting. MedlinePlus+1

This guide explains why you have nausea during ovulation, other medical causes of nausea and how to identify if your nausea is due to pregnancy or not.

What causes nausea during ovulation?

If you are experiencing nausea during ovulation, it’s likely nothing to worry about if it is mild and short-lived. Here are common causes you should know.

1. Hormone change during ovulation

During your menstrual cycle, different hormones will rise and fall to ensure ovulation takes place.

At the start of your menstrual cycle, estrogen, which is produced by the follicular cell of the ovaries, will continue to rise.

Around ovulation, estrogen levels drop with an increasing level of luteinizing hormone (LH). Hours after the LH surge, ovulation will occur.

If you get nausea around this time, don’t panic. Ovulation nausea usually lasts for a short time (hours to a few days).

2. Pain and nausea

Having ovulation means your ovaries are working normally and releasing an egg into the fallopian tube.

During ovulation, some women will feel pain in their abdomen (ovulation pain or mittelschmerz). If the pain is strong, it may trigger nausea, low back pain or even mild dizziness in some women. Ovulation pain (mittelschmerz) is common and usually harmless, but severe or sudden pain needs a check-up. Cleveland Clinic

Very strong, one-sided pain with nausea and vomiting can also be caused by other conditions like ovarian cysts, ovarian torsion, endometriosis, appendicitis or even an ectopic pregnancy, not just normal ovulation. If the pain is severe, different from your usual pattern, or you feel very unwell, you should see a doctor urgently. Cleveland Clinic

3. Drugs you’re taking

There are certain medications you are currently taking that would make you have nausea and vomiting.

Antibiotics, antidepressants, vitamins, iron supplements, non-steroidal anti-inflammatory drugs (NSAIDs) — aspirin, ibuprofen, naproxen — and some hormonal medicines can cause you to feel nauseous.

If you are uncertain of what medications you’re ingesting, it’s necessary you consult with your doctor or pharmacist regarding likely side effects.

Then again, if you’ve been diagnosed with cancer, chemotherapy drugs often cause nausea and vomiting. Usually, anti-nausea drugs are given to ease nausea and vomiting when on these medications. Cancer.gov

Also, if you are currently on drugs to boost fertility, like Clomid, or other fertility injections, there is a chance you could feel nauseous. It’s vital you take nothing for granted and see your physician for advice, especially if your nausea becomes severe.

4. Stomach flu

Feeling nauseous may sometimes be due to stomach flu (viral gastroenteritis) or food poisoning. If you’ve taken contaminated food and water, you are likely to have gastroenteritis that affects your stomach and intestines. This may cause some women to have nausea.

Other symptoms of stomach flu are vomiting, abdominal pain, diarrhoea and fever, and it usually settles within a few days with rest and fluids. nhs.uk+1

5. Gastroesophageal reflux disease (GERD)

GERD means, after eating, some stomach content is pushed back into your esophagus (food pipe). Symptoms are feeling nauseous, vomiting, chest pain, sour taste, and heartburn. Chronic acid reflux or acid reflux and GERD can irritate the esophagus over time and may need treatment. Cleveland Clinic

GERD is quite common and affects a significant number of adults worldwide. Talk to your doctor if any of the above symptoms show up, especially if you also have trouble swallowing, weight loss, or chest pain.

How to stop nausea and vomiting during ovulation

If you are getting nauseous during your ovulation period, it’s important to detect why it’s happening. If it’s due to hormone changes during your menstrual cycle, in a few days, you will usually start feeling better.

On the other hand, stomach flu, food poisoning, pregnancy, or other medical problems may make you nauseous for many days.

See a doctor or go to the hospital urgently if:

• You cannot keep any food or liquid down for more than 24–48 hours

• You have severe one-sided pelvic pain, shoulder pain, or feel dizzy/faint (could be ectopic pregnancy or torsion)

• You have high fever, very strong abdominal pain, or vomit blood or material that looks like coffee grounds

• You are pregnant (or might be) and vomiting many times a day or losing weight

If you currently feel mild nausea, you can try one of these simple methods that may help. These tips are also similar to those advised for nausea and vomiting in general. MedlinePlus

1. Use Ginger

If you’re having nausea or vomiting during ovulation, you can try one of the oldest and reliable methods that still works for many people.

Ginger may help reduce nausea feeling, relax stomach muscles, and support digestion. It is commonly used for motion sickness and pregnancy-related nausea and is generally considered safe in small amounts. NCCIH+1

How to prepare ginger for nausea treatment

• Get ginger, wash to ensure it’s clean, peel and cut into small pieces.

• You can continue to chew small pieces throughout the day every few hours.

• You can also prepare ginger tea or purchase a snack that contains ginger.

If you are pregnant or on blood-thinning medicines, talk to your doctor before taking ginger supplements. You can read more about ginger from NCCIH. NCCIH

2. Use pyridoxine (vitamin B6)

In women who are having severe nausea and vomiting, taking vitamin B6 can help make you feel better, especially in early pregnancy when prescribed by a doctor. Typical doses used for nausea in pregnancy are around 10–25 mg up to 3 or 4 times daily, and total daily doses above about 100 mg should be avoided long term because of nerve-related side effects. Lippincott Journals+1

Always talk to your doctor before starting vitamin B6 if you might be pregnant, are already on other medicines, or have kidney or nerve problems.

3. Use anti-nausea drugs

Please note: Talk to your doctor before you start medications to stop nausea. Some of these medications could affect your baby if you are actually pregnant, and many are not recommended or need special dosing in pregnancy or if you have other health problems.

The common types of prescription nausea drugs used are promethazine, ondansetron, and metoclopramide. For pregnant women, most guidelines advise starting with lifestyle changes and vitamin B6 (sometimes combined with doxylamine), and then adding stronger anti-nausea medicines only when needed under medical supervision. acog.org+1

Is nausea during ovulation a sign of pregnancy?

The truth is, if you’ve not had sexual intercourse during your fertile window, nausea at any time during your menstrual cycle is not due to pregnancy. To get pregnant, sperm will fertilize the ovum from the woman, resulting in pregnancy.

Your fertile window is usually the few days before ovulation and the day of ovulation itself, because sperm can live in the female genital tract for up to 5 days. If there was no unprotected sex at all in that period, pregnancy is extremely unlikely.

On the other hand, if you experience nausea after weeks of unprotected sexual intercourse, it may be due to pregnancy. Nausea is usually more noticeable from around the time of a missed period.

One sign experienced by some women during early pregnancy is light vaginal spotting that is pink or brown in colour. This spotting (sometimes called implantation bleeding) may take place about 6–12 days after ovulation and a few days before your next menses. Not all women have this, and heavy or bright red bleeding is not typical and should be checked. acog.org+1

A lot of women may not recognize implantation bleeding, and nausea or a missed period may be the first noticeable pregnancy sign.

You should test in a clinic close to you or with a home pregnancy test once your period is late and confirm if you are pregnant or not.

Other pregnancy symptoms are:

• Breast pain, itching, and soreness

• Mood change

• Food aversion

• Fatigue

How long does ovulation nausea last?

During ovulation, you will experience different symptoms which can include watery discharge, increased sexual drive, bloating, and breast pain.

Some women will experience belly cramps too. If you get nausea related to ovulation, it usually does not last for long — often from a few hours up to 1–2 days, and should improve on its own. Cleveland Clinic

Don’t forget; some women will experience nausea within two weeks before their period as part of premenstrual syndrome (PMS), while for others this may be an early pregnancy sign. Nausea alone cannot reliably tell the difference, so a pregnancy test is still important if your period is late.

If you have a fever, feel weak, have persistent vomiting or diarrhoea, or your symptoms last more than 48 hours, inform your doctor. MedlinePlus+1
