The third trimester brings you to the finish line. As your due date approaches, knowing what to expect helps you feel prepared for labor, delivery, and meeting your baby.
Weeks 28-32: The Home Stretch Begins
Your baby is now considered viable—if born early, with medical intervention, survival rates are excellent. Brain development accelerates dramatically, and your baby can now dream during REM sleep. Movements might feel different as space tightens, but you should still feel regular daily movement.
Physical discomfort peaks during this period. Heartburn intensifies as baby pushes against your stomach. Shortness of breath occurs as the uterus presses against your diaphragm. Finding comfortable sleeping positions becomes challenging—special pregnancy pillows help. Hemorrhoids, swelling in feet and ankles, and frequent urination all increase.
Weeks 33-36: Preparing for Birth
Your body begins preparing for labor. The baby drops lower into your pelvis (lightening or "engagement") for first-time mothers, relieving some upper abdominal pressure while increasing pelvic pressure. Braxton Hicks contractions become more frequent and may feel intense.
Many healthcare providers begin weekly appointments now. Group B streptococcus (GBS) testing happens around 36 weeks. Start packing your hospital bag and finalizing birth preferences. Consider cord blood banking if you're interested.
Weeks 37-40: Full Term and Beyond
At 37 weeks, your pregnancy is considered early term—baby is fully developed and ready for life outside the womb. First-time moms often go past their due date, while subsequent pregnancies tend to arrive earlier. Your body may give hints that labor is approaching: bloody show, nesting instinct, diarrhea, or regular contractions.
Learning to recognize true labor versus Braxton Hicks is crucial. True labor contractions become regular, progressively stronger, and don't stop with movement or hydration. When contractions are 5 minutes apart, lasting 1 minute each, for at least 1 hour, it's time to call your provider.
Signs of Labor
Water breaking (rupture of membranes) happens before labor begins in about 10-15% of pregnancies. When it occurs, note the time and call your provider—most women go into labor within 24 hours. If contractions haven't started, induction may be discussed.
Other labor signs include regular contractions, lower back pain that wraps around to the front, and the mucus plug passing (which can happen days before actual labor). Trust your instincts—if something feels different, contact your healthcare provider.
What to Pack
Pack your hospital bag by 36 weeks. Essentials include: comfortable clothes, nursing bras, toiletries, phone charger, going-home outfit for baby, and car seat. Bring snacks for your partner and consider packing your own pillow. Include your birth plan and any needed paperwork.
For baby, hospitals typically provide diapers, wipes, and basic necessities during your stay. Focus on comfortable clothes for going home and a properly installed car seat.
Mental Preparation
It's normal to feel anxious about labor and parenthood. Reading positive birth stories, taking childbirth classes, and practicing relaxation techniques help manage fear. Discuss pain relief options with your provider ahead of time so you know what's available.
Remember that your body was designed for this. Trust your instincts, lean on your support team, and focus on meeting your baby soon.
