Felicitations, you’re halfway along! Another 20 weeks and mini-you will be cooing in your arms. Let’s look at new ideas for painting the nursery now! (make the mother stay away from the paints though!)
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 reaches near the level of your belly button around this stage. As it expands upward, it changes posture, balance, and the way surrounding muscles support your body. Blood circulation continues increasing to sustain rapid development.
Kicks may begin feeling more consistent now, especially during quiet moments or at night. You may also notice round ligament pain, lower back strain, or increasing appetite.
Your baby’s muscles continue strengthening, making movements easier to feel consistently. Hair, eyebrows, and eyelashes are becoming more visible, while swallowing and movement practice continue daily. The body is now growing more proportionately.

Each week brings new things to prepare for. Here's what expecting parents during week 20 typically track in the BabySteps Companion app. Items are sorted by priority so you can focus on what matters most.

At 20 weeks pregnant, some expecting moms find they have a higher sex drive and better orgasms because of increased blood flow and lubrication. For most women, sex during pregnancy is completely safe and beneficial – it helps you stay active, releases hormones that make you happy and relaxed, and facilitates a close bond with your partner. If your belly is starting to get in the way, experiment with pregnancy sex positions that will accommodate your bump.

Pregnancy hormones can affect hair and nail growth and texture. Some women experience thicker, shinier hair, while others may notice changes in hair texture or increased shedding after childbirth.

Read moreHeartburn, or acid indigestion, is common during pregnancy due to hormonal changes and pressure from the growing uterus on the stomach. To help relieve heartburn, eat small, frequent meals, avoid spicy or acidic foods, and sit up after eating. If heartburn persists or becomes severe, consult your healthcare provider for advice on safe treatment options during pregnancy.
Read moreIt's common to experience a boost in appetite during pregnancy due to hormonal changes and the increased energy needs of your growing baby. To satisfy cravings and maintain a balanced diet, focus on nutrient-rich foods like fruits, vegetables, lean proteins, and whole grains. However, be mindful of portion sizes to prevent excessive weight gain. If you have concerns about your appetite or dietary habits, consult your healthcare provider for guidance.
