Pregnancy Week 36: What to Expect

Baby's development, your body's changes, common symptoms, what to eat, and what to do this week.

Baby's size this week: Romaine lettuce (~46 cm; about 5.5-6 lb)

Baby's development at week 36

Baby is mostly fully developed. Final surfactant production for lungs. Baby is gaining weight — fat fills in. Most babies are head-down by now. Baby's brain is in major growth mode. Baby is "early term" starting at week 37, but most babies stay in until 39-41 weeks.

What's happening in your body

Your uterus is about 6.5 inches above the belly button. Possible "lightening" — baby drops lower in the pelvis, which means less heartburn and breathing room but more pelvic pressure, frequent urination, and pelvic discomfort. The mucus plug may start to pass. Possible Braxton Hicks contractions more regularly.

Common symptoms at week 36

Pelvic pressure. Lightening (baby drops). Possible mucus plug passing — clear, pink, or brown gooey discharge, in pieces or all at once. Possible Braxton Hicks. Possible bloody show — pinkish discharge with mucus. Strong fetal movements. Sleep very difficult.

When to call your provider

Watery gush or trickle (water breaking) — call provider, but baby is full enough to be born. Painful regular contractions (every 5 minutes for an hour, increasing intensity). Bright red bleeding (not "show" pink). Severe headache/vision changes.

How to feel better this week

Take final prenatal classes. Confirm childcare for older kids during labor. Confirm dog/pet care. Confirm who is on the "I am in labor" call list. Pack snacks for the hospital. Continue everything else.

Nutrition focus for week 36

Continue all nutrients. Some research suggests dates (the fruit) — 4-6 per day starting at week 36 — may help soften the cervix and reduce labor duration. Worth trying if you like them. Continue hydration, iron, calcium.

For your partner

Finalize the "I am in labor" plan together. Confirm childcare, pet care, "what to do when" list.

This week's to-do

Finalize labor logistics. Take final classes. Eat dates if you want.

Is this normal?

"Bloody show" — pinkish discharge with mucus — can happen days or weeks before active labor. It is not labor itself, just a sign things are progressing.
