> At 28 weeks pregnant, frequent urination, especially at night, often becomes more noticeable as your baby grows and places increased pressure on your bladder.

At 28 weeks pregnant, as you step firmly into your third trimester, the experience of frequent urination often takes on a new dimension compared to earlier stages. While you might have noticed an increase in restroom trips in your first trimester, perhaps alongside other shifts like [Food Aversions at 8 Weeks Pregnant](/pregnancy/symptoms/food-aversions-week-8), this third-trimester frequency is largely a direct result of your growing baby's presence and position.

This week, your body is managing a significant increase in blood volume—up to a 50% rise—which means your kidneys are working harder to process fluids, leading to more urine production. Concurrently, your uterus has expanded considerably, and your baby is now larger, directly contributing to increased pressure on your bladder. This physical compression can make the urge to urinate feel more constant and immediate. Many parents find this symptom becomes particularly noticeable at night, disrupting sleep as the baby's position shifts and pressure on the bladder intensifies when lying down. It's a common, if sometimes inconvenient, part of this stage of pregnancy.

Maintaining adequate hydration throughout your day remains incredibly important for your overall well-being and to support your increased blood volume. While the thought of more restroom visits might tempt you to reduce fluid intake, especially if you've been navigating shifts like [Food Aversions at 10 Weeks Pregnant](/pregnancy/symptoms/food-aversions-week-10) that can impact your fluid preferences, staying hydrated is essential. One practical approach many find helpful is to front-load your fluid intake earlier in the day and consciously reduce it a few hours before bedtime. This can help minimize those nighttime trips without compromising your essential daytime hydration.

It's also important to pay attention to any changes in how urination feels. While frequent trips are a normal part of pregnancy, especially now at 28 weeks, any pain or burning sensation during urination warrants a conversation with your care provider. Research indicates that urinary tract infections (UTIs) affect a percentage of pregnancies and require prompt treatment. Additionally, a condition known as asymptomatic bacteriuria, where bacteria are present without noticeable symptoms, also requires treatment during pregnancy—a unique guideline for expectant parents. Just as you might have monitored other subtle body changes in early pregnancy, such as those that could lead to [Food Aversions at 12 Weeks Pregnant](/pregnancy/symptoms/food-aversions-week-12), being attuned to your urinary health is a key aspect of informed self-care now. Your provider is your best resource for your specific situation and can offer guidance if you have any concerns about your urinary health.
