Week 14: Welcome to the Second Trimester

Your baby's neck is becoming more defined, allowing the head to hold a more upright position rather than resting directly on the chest. Tiny facial muscles are developing enough that your baby may already be practicing squints, frowns, and even faint smiles — all reflexive at this stage, not yet emotional responses.

Lanugo, a fine, soft hair, is starting to cover your baby's body. This downy layer helps regulate body temperature in the womb and usually sheds before or shortly after birth.

Your baby's liver, kidneys, and other organs continue maturing, and the production of red blood cells has now fully shifted to the spleen and liver from the earlier yolk sac stage.

If you're expecting a girl, her ovaries already contain millions of immature egg cells at this point — far more than she'll ever actually use across her lifetime.

This is often when the dreaded first-trimester fatigue and nausea start to genuinely lift for many women, replaced by a noticeable boost in energy. Your uterus is now about the size of a small cantaloupe and has risen well above the pelvic bone, which is often when a true baby bump becomes visible.

Increased blood flow can give you a noticeable "pregnancy glow," though it can also mean more visible veins and, for some, mild nasal congestion due to swollen blood vessels in the nasal passages — sometimes called "pregnancy rhinitis."

Common symptoms during week 14 include:

• Renewed energy and appetite for many women
• A more visible baby bump
• Mild nasal congestion or occasional nosebleeds
• Continued round ligament discomfort as the uterus stretches
• Increased vaginal discharge (leukorrhea)
• Occasional headaches
• Skin changes, including some early stretch marks for certain women

Many women describe the second trimester as feeling like a different pregnancy altogether compared to the rough patches of the first trimester.

With appetite returning for many, this is a great time to build sustainable, balanced eating habits. Aim for a mix of complex carbohydrates, lean protein, healthy fats, and plenty of fruits and vegetables across the day.

Iron needs increase significantly during the second trimester to support your growing blood volume. Good sources include lean red meat, beans, lentils, spinach, and fortified cereals — pair iron-rich plant foods with vitamin C (like citrus or bell peppers) to improve absorption.

Continue avoiding raw or undercooked meat, fish high in mercury, unpasteurized dairy, and excessive caffeine.

If your energy has returned, this is often the best window of pregnancy to build or maintain an exercise routine. Walking, swimming, stationary cycling, and prenatal yoga are all excellent low-impact choices.

As your bump grows, you'll gradually want to avoid exercises that involve lying flat on your back for extended periods, since the weight of the uterus can compress major blood vessels. Side-lying modifications are usually easy to make.

Things to keep in mind this week:

• Schedule your anatomy scan appointment if you haven't (typically done 18-22 weeks)
• Discuss your iron intake and whether a supplement is needed, based on bloodwork
• Start researching childbirth classes if you're interested — many fill up early
• Continue your prenatal vitamin routine

Routine prenatal visits in the second trimester are typically spaced about 4 weeks apart for low-risk pregnancies. Your provider will check your weight, blood pressure, urine, and measure your growing belly (fundal height) starting around now or shortly after.

This is a good time to ask about the detailed anatomy ultrasound coming up in the next several weeks — it's one of the most anticipated appointments for many parents.
