The countdown is on!
At 28 weeks, you enter your third trimester. For most people, the third trimester often brings a mix of emotions and feelings. Excitement, anticipation, frustration, and fatigue can all be common.
What to expect physically
You and your baby will experience significant changes and growth. Most babies triple their weight, or more, during these final weeks — on average half a pound per week. All this growth can take its toll on your body.
You may feel tired, have back or joint pain, and heartburn. This time in pregnancy is also when you are at the highest risk of developing pregnancy-related high blood pressure. Preeclampsia is also a pregnancy-related condition. Signs of preeclampsia include headaches, vision changes, chest pain, shortness of breath, pain in the upper right part of your abdomen, or just feeling “off.” If you notice any of these, contact your healthcare provider.
Braxton Hicks, or practice, contractions, are common as your body gets ready for labor. If they get stronger or more regular, or if you notice bleeding or fluid leaking, contact your provider.
What to expect emotionally
It’s common to feel anxious about parenthood or the impact another child may have on the current family dynamic. As providers screen for things like gestational diabetes, pregnancy-related hypertension, anemia, and Group B Strep, many parents may feel worried or overwhelmed. While these feelings are very normal, they shouldn’t be ignored.
About 15 to 20 percent of pregnant people have more serious symptoms of depression or anxiety before or after birth. While many find good support in their family and friends, talk to your provider if these feelings and stressors become too much. They can connect you with resources and mental health professionals to help you.
