In the midst of highly accomplished weeks in terms of growth and development, pat yourself (and your partner) on the back for making it to where you are currently.

Second Trimester is a time of rapid change — for both you and your baby. Every pregnancy is unique, and the information below will help you understand what's happening and how to prepare for the weeks ahead.
Your uterus expands further into the abdomen, changing posture and shifting your center of gravity. Increased circulation supports growth but can also contribute to swelling, headaches, or occasional dizziness. Your body is now visibly adapting to accommodate the pregnancy.
You may begin feeling more distinct fluttering or movement sensations around now. Lower back tension, nasal congestion, or mild swelling can also begin appearing more regularly.
The ears are now positioned closer to their final location, and your baby may begin hearing muffled internal sounds like your heartbeat and digestion. Muscles continue strengthening, allowing more active twisting, kicking, and stretching movements.
Each week brings new things to prepare for. Here's what expecting parents during week 18 typically track in the BabySteps Companion app. Items are sorted by priority so you can focus on what matters most.

At this visit, your doctor will continue to check your weight, blood pressure, and urine. They will also listen to your baby's heartbeat and do ultrasounds to check the baby's development.
Research breast pump options, as some may be covered by your insurance. Understanding the types available and their features empowers you to make an informed choice that suits your needs.

Every pregnancy is different, but these are some of the most common sensations women report during week 18. Your experience is valid — whether you feel all of these or none at all.
During pregnancy, hormonal changes can increase oil production in the skin, leading to acne breakouts. To manage acne, wash your face twice daily with a gentle cleanser, avoid harsh skincare products, and use non-comedogenic moisturizers and makeup. If acne persists or worsens, consult your healthcare provider for safe treatment options during pregnancy.

During pregnancy, hormonal changes can slow digestion, leading to bloating. Eating smaller, more frequent meals can help alleviate discomfort. Gentle exercise and staying hydrated may also help improve digestion. If bloating becomes severe or persistent, consult your doctor for advice.

Your growing uterus puts pressure on your bladder, which can make you feel like you need to pee more often. While frequent urination is normal, it's essential to stay hydrated and empty your bladder regularly to prevent urinary tract infections. If you experience pain, burning, or other symptoms along with frequent urination, consult your healthcare provider for evaluation and treatment.
