Week 14 of Pregnancy
Learn about your baby's development and what to expect at 14 weeks pregnant.
Baby's Size This Week
Baby Development at Week 14
- ● Your baby is about 8.7 cm long and weighs approximately 43g — roughly the size of a peach.
- ● Facial features are becoming more defined — the eyes have moved closer together, and the ears have reached their final position.
- ● Your baby is now producing thyroid hormones independently, which are crucial for brain development and metabolic regulation.
- ● Lanugo (fine, downy hair) is beginning to cover the entire body to help regulate temperature and hold vernix later.
- ● The roof of the mouth (palate) has fully fused, and the sucking reflex is actively developing through swallowing movements.
- ● Your baby is becoming increasingly active — stretching, yawning, making grasping motions, and practicing facial expressions.
Your Body at Week 14
- ● Energy levels are improving significantly, and many women feel the best they have since becoming pregnant.
- ● Your bump may be starting to show visibly, especially in tighter clothing or if this is not your first pregnancy.
- ● Nasal congestion and occasional nosebleeds may occur due to increased blood volume and swollen nasal membranes.
- ● You may notice improved skin texture and thicker, shinier hair thanks to elevated estrogen and prenatal hormone levels.
- ● Appetite increases noticeably as nausea fades — this is a good time to refocus on nutrient-dense eating habits.
- ● Mild headaches may continue, often related to hormonal shifts, caffeine changes, dehydration, or tension.
Week 14 Checklist
- ☐ Schedule your mid-pregnancy anatomy ultrasound for weeks 18-22 if you have not done so already.
- ☐ Begin doing pelvic floor exercises (Kegels) at least 3 sets of 10 repetitions daily if you have not started.
- ☐ Consider starting a regular pregnancy exercise routine — swimming, walking, and prenatal yoga are excellent choices.
- ☐ Update your dental care — schedule a cleaning if you have not had one since becoming pregnant.
- ☐ Begin building your baby registry and researching major purchases (crib, stroller, car seat) with safety ratings in mind.
- ☐ If you are planning to travel, the second trimester is generally the most comfortable and lowest-risk time.
Frequently Asked Questions
Is it safe to travel during the second trimester?
The second trimester (weeks 13-27) is generally the safest and most comfortable time to travel. Morning sickness has usually subsided, energy is higher, and the risk of complications is lowest. Fly comfortably, stay hydrated, walk around regularly, and carry medical records. Most airlines allow flying until 36 weeks. Discuss travel plans with your provider, especially for international trips.
How much weight should I gain during pregnancy?
Recommended weight gain depends on your pre-pregnancy BMI: underweight (28-40 lbs), normal weight (25-35 lbs), overweight (15-25 lbs), obese (11-20 lbs). In the first trimester, expect 1-4 lbs total. In the second and third trimesters, aim for about 1 lb per week. These guidelines are from ACOG and are averages — discuss your specific goal with your provider.
Why is my hair so thick during pregnancy?
Rising estrogen levels prolong the growth phase of hair, meaning fewer hairs fall out than usual. This makes hair appear thicker and fuller. You may also notice faster nail growth. This effect is temporary — after delivery, hormone levels drop and the extra hair sheds (postpartum hair loss around 3-6 months after birth), which is normal.
When should I start buying baby gear?
The second trimester is a good time to start researching and purchasing big-ticket items like a crib, car seat, and stroller. Create your registry around 16-20 weeks so friends and family have time to purchase gifts. Essentials like a car seat and safe sleep space should be ready by 36 weeks. Do not feel pressured to buy everything at once — prioritize safety items first.
What is lanugo and does my baby really have hair all over?
Lanugo is the fine, soft, downy hair that covers your baby's body beginning around week 14. It helps anchor the vernix caseosa (protective waxy coating) to the skin and may also help regulate body temperature in the womb. Most lanugo is shed before birth, between weeks 36-40, though some babies (especially preterm) are born with patches still present, which falls off within a few weeks.
