Should you be worried about your cloudy urine?

Has your urine has become cloudy lately? Should you be worried about your unborn baby?

Cloudy urine during pregnancy can be enough to freak out any expectant mom. After all, we’ve all known women who’ve had complications develop during pregnancy.

Does this mean you’re going to join their ranks? Or could cloudy urine be just a minor speed bump in your quest for a safe delivery?

While your pee may seem like a harmless substance, sometimes it can be a crystal ball into the health of your pregnancy.

If you won’t rest until you play Nancy Drew and solve the mystery of the cloudy pregnancy urine, we’ve got your back. Let’s play super sleuth for you so you can get some much needed stress-free rest.

Is Cloudy Urine in Pregnancy Common?

While we hate to think of anyone else suffering the same anxiety we do about cloudy-looking pee, there is some comfort in hearing other women have also had that problem. When it comes to cloudy urine, you can rest easy — it’s a common problem for pregnant women (1).

Lots of women have stared into the abyss of their toilet, squinting to determine if they see some cloudiness in their urine. Often, they’re right. That cloudiness is there.

But you know what? Many healthy babies have been born, despite their mothers’ cloudy urine. So try not to stress out about it, even though it’s hard.

Causes of Cloudy Urine During Pregnancy

There are quite a few reasons a pregnant woman might have cloudy urine. Some of those causes aren’t a reason for alarm and others warrant a trip to the doctor.

It’s okay to take a little while to figure out at home what might be causing your cloudy urine. But if you notice any other symptoms, you should call your doctor immediately. Even if it turns out to be nothing, your doctor should be kept in the loop.

Now you know not to be a hero when you’re facing a possible medical problem, let’s look at some of the potential causes for your problem.

Pregnancy Hormones

When you first suspected you were pregnant, you likely peed on a pregnancy test stick to find out for sure. Those tests work because they measure the Human Chorionic Gonadotropin levels in your urine. This hormone is produced in pregnancy and for the first trimester, its level increases quickly.

The Most Likely Cause

When you pee, the hormones can come out and make your urine appear cloudy. It’s harmless and it will pass by the time your second trimester rolls around.

If you see cloudy urine in your first trimester, mention it to your doctor. They may want to rule out other causes, but, breathe easy, it could be as harmless as pregnancy hormones.


If you aren’t drinking enough water, you may notice cloudy urine. In addition to cloudiness, your pee will also be darker in color.

If you notice both cloudiness and a dark color when trying to judge how healthy your urine looks, drink a big glass of water. Then check later in the day if it has improved things.

Urinary Tract Infections

Urinary tract infections are a common problem for women, even when they are pregnant. In fact, you’re more likely to get them during pregnancy. You’ll have a higher chance of getting one between weeks 6 through 24 of your pregnancy because your growing uterus can stop you from fully emptying your bladder.

If you have pain or burning while peeing or feel like you have to pee more frequently, suspect a UTI. Other symptoms you may have include chills, fever, or cramping in the low abdomen (2).

If you suspect a UTI, get into your OB’s office for an examination as soon as possible. They’ll test your urine and if you do have a UTI, give you a course of antibiotics.

Too Much Protein in Your Urine

Another cause of cloudy urine is too much protein in it. Women in later stages of pregnancy, anywhere from four to nine months, are at an increased risk of having this happen.

Sometimes, excess protein in your urine can signal preeclampsia, which is a dangerous condition for you and your baby. It can cause severe consequences like kidney damage and elevated blood pressure, and even be life-threatening (3).

If you are leaving urine at each OB appointment, your OB provider is likely checking your urine for protein. They will keep close tabs on you if you have too much protein in your urine, to ensure you aren’t developing preeclampsia. If you’re concerned your cloudy-looking urine could be preeclampsia, look for other signs you can discuss with your doctor.

One sign is swelling in your hands, face, or feet. Another common sign is excessive weight gain in one week — it could be more than four pounds. The sudden weight gain is usually caused by all the fluid your body is retaining.

Take Note

Protein in the urine also causes bubbly urine so if you see bubbles and cloudiness, see your doctor or midwife to find out if there is protein in the urine.

Diet Changes

Pregnant women are often at the mercy of their food cravings. When I was pregnant, I wanted chocolate and french fries all the time. I didn’t let myself eat them at every meal, although I would have liked to if I wasn’t watching my weight.

Sometimes, you get on a kick with a certain food and want to eat nothing else for a day or two straight.

Keep In Mind

If you make an abrupt change to your diet, you might be setting the stage for cloudy urine. Certain foods, like asparagus and dairy products, may make the matter worse.

If you think your diet could be causing your cloudy urine, try eating healthy consistently, and see if it goes away.


You might not want to think about this one, but pregnancy doesn’t make you immune to sexually transmitted diseases. Gonorrhea is one of those diseases and it can make your urine cloudy.

Unfortunately, this disease is on the rise in the U.S. with over 580,000 million people being diagnosed in 2019 (4).

Gonorrhea can be treated with antibiotics, but if you don’t seek treatment when you have a suspected case, it can cause serious consequences for you and your baby. Signs you may be fighting gonorrhea include painful urination and a lot of vaginal discharge. Unfortunately, gonorrhea and other STDs can have no symptoms at all. Make sure you are getting regular prenatal care and vocalizing any concerns about unsafe sex to your OB provider.

Vitamin Overload

Extra vitamins are a good thing during pregnancy because you and your baby can benefit from them. No wonder it is so important for women to take their prenatal vitamins.

Usually, those vitamins give you neon yellow urine, but it’s also possible they could make your urine appear cloudly. The two biggest culprits are vitamins C and B.

How Quickly Should I Act?

Rather Safe Than Sorry

Pregnancies can quickly take a turn for the worse, seemingly out of nowhere, particularly in the case of preeclampsia. For that reason, it’s always best to put all your cards on the table with your doctor right away.

Some moms-to-be don’t like to call when they’re worried about something because they’re afraid to feel ridiculous if it turns out to be nothing. They may also worry about missing one more half-day at work to attend yet another pregnancy appointment.

I used to feel the same way, but I had to remind myself I was now responsible for two people constantly; I couldn’t dismiss any concerns.
So, if you notice cloudy urine, call the OB office and let them sort it out for you.

Keeping It Together

It can be hard to keep your composure when you notice concerning changes, like cloudy urine. But you’ve made it this far and if you pay close attention to the signs from your body, you’ll be fine.

Cloudy urine is common among pregnant women and can be due to a variety of reasons. Some of these, like pregnancy hormones, diet changes, and dehydration, are fairly harmless and can be rectified at home. Others still like gonorrhea, a UTI, or too much protein may require a visit to your doctor.

Watch out for other symptoms like pain or burning during urination, swelling of the face or limbs, and excessive vaginal discharge. Never be afraid to call your doctor if you feel concerned about the state of your urine. It is, after all, a crystal ball for your pregnancy health.
