What's Happening With Your Baby
The last week of the second trimester. The baby gets hiccups regularly — you may feel them as rhythmic twitches. Brain tissue is developing quickly. Sleep cycles have become well defined.
What's Changing For You
You're heading into the third trimester. Fatigue can return. Leg cramps and swelling may increase.
To Do This Week
Your appointments will become more frequent — review your schedule.
Notice the hiccups: regular, rhythmic twitches are normal and nothing to worry about.
Sort the nursery and your shopping now rather than tiring yourself in the final weeks.
Frequently Asked Questions
How many months is 27 weeks pregnant?
Week 27 of pregnancy falls in month 6 and in the second trimester. Pregnancy months don't run in neat four-week blocks, so the week-to-month conversion rarely lands on a whole number — which is why pregnancy is tracked in weeks.
How big is the baby at 27 weeks?
At 27 weeks your baby is roughly the size of a cabbage: around 36.6 cm long and 875 grams. These are averages; clear variation between babies is normal, and what matters is the growth curve your doctor is tracking.
How long is left at 27 weeks pregnant?
Assuming a 40-week pregnancy, you have around 13 weeks left at week 27. Most births happen between weeks 37 and 42, so a due date is a range rather than a fixed day.
What should I watch out for at 27 weeks?
Your appointments will become more frequent — review your schedule. Notice the hiccups: regular, rhythmic twitches are normal and nothing to worry about. Sort the nursery and your shopping now rather than tiring yourself in the final weeks.

When To Seek Care Immediately
Whatever week you are in, contact your doctor or the nearest health facility without waiting if you have: vaginal bleeding or fluid loss, severe persistent abdominal pain, a severe headache, blurred vision or flashing lights, sudden swelling of the hands or face, a fever above 38 °C, burning on urination with fever, persistent vomiting, fainting, or — after week 28 — a clear reduction in your baby's movements. In these situations reach real medical care rather than an app or a web search.
