The end of this week marks your biggest breakthrough. The third trimester finally begins bringing with itself new joys, and jitters, to your journey. We are so proud of you for making this far. We are here to answer all your questions, as big as your bump or as small as your baby. Buckle up, hardly 3 months to go!
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 continues pressing upward against the diaphragm and outward against abdominal muscles. Circulation, metabolism, and fluid retention all increase as your body supports continued rapid fetal growth. The physical demands of pregnancy become much more noticeable now.
You may feel stronger kicks, tighter abdominal stretching, or more pressure on the ribs and pelvis. Fatigue often returns around now, even after lighter activity.
Brain development accelerates significantly this week, creating more complex neural connections. The lungs continue maturing, while body fat helps smooth and round out the skin. Movements may feel stronger, sharper, and more predictable now.

Each week brings new things to prepare for. Here's what expecting parents during week 27 typically track in the BabySteps Companion app. Items are sorted by priority so you can focus on what matters most.

Every pregnancy is different, but these are some of the most common sensations women report during week 27. Your experience is valid — whether you feel all of these or none at all.
Some pregnant women experience diarrhea due to hormonal changes or dietary adjustments. It's essential to stay hydrated if you're experiencing frequent bowel movements. However, if diarrhea persists for more than a day or is accompanied by other symptoms like fever or abdominal pain, contact your healthcare provider.

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.
Read moreHormonal fluctuations during pregnancy can lead to mood swings, characterized by sudden changes in emotions, ranging from happiness to sadness or irritability. It's essential to communicate openly with your partner and healthcare provider about your feelings and concerns. Engaging in relaxation techniques, maintaining a healthy lifestyle, and seeking support from loved ones can help manage mood swings during pregnancy.
Read moreNosebleeds are common during pregnancy due to increased blood volume and hormonal changes. To help stop a nosebleed, sit upright and lean forward, pinching your nostrils together for several minutes. If nosebleeds are frequent or severe, consult your healthcare provider for advice.
Read moreThe round ligaments are two bands of tissue that support the uterus. As your uterus grows, the round ligaments can stretch, which can cause pain in the lower abdomen or groin area. To relieve round ligament pain, try changing positions, practicing gentle stretches, and applying heat or cold packs. However, if pain is severe or persistent, consult your healthcare provider.
Read moreThese are pink or purple streaks that can appear on your abdomen, breasts, thighs, and buttocks. They are caused by the rapid stretching of your skin to accommodate your growing baby. While they're a natural part of pregnancy, keeping the skin well-moisturized with creams or oils can help minimize their appearance. However, it's important to remember that stretch marks are normal and fade over time.
