Monthly highlights
- 1Baby’s Development. By month 9, your baby is nearly ready for birth, likely weighing around 6–9 pounds and measuring 18–20 inches. Lungs mature until delivery, and weight gain continues at about half a pound per week. Most babies turn head-down, though breech positions may require monitoring or intervention.
- 2Bodily Changes & Symptoms. Frequent urination, swelling, back pain, pelvic pressure, stretch marks, and tingling hands are common. Relief can come from elevating your feet, using good posture and supportive shoes, resting when possible, and wearing liners for leaks.
- 3Health & Wellness. Expect Group B strep screening, with antibiotics during labor if positive. Learn to distinguish Braxton Hicks from true labor, and call your provider if contractions become regular, your water breaks, or bleeding occurs. Fundal height usually matches your weeks of pregnancy.
- 4Tips & To-Dos. Pack your hospital bag, practice the route, and finalize baby gear and nursery prep. Review pain relief and induction options with your provider, stock newborn essentials, and arrange meals, childcare, and home help for after birth.

Key Takeaways
Yes! The end of your pregnancy is in sight now, and the big day approaches. Keep in mind that your little one isn’t technically considered full term and ready for birth until 39 weeks and that only about 1 in 20 women give birth on their exact due date. So, you both may have a few more weeks of growing to do, but you’re almost there! Read on to learn more about the kinds of things that are in store for you when you’re nine months pregnant.
Common Pregnancy Symptoms at 9 Months Pregnant
When you’re nine months pregnant, some of the normal pregnancy symptoms you might experience include:
How Is Your Baby Developing This Month?
Your baby’s lungs develop right up until birth as they get ready for her first breath and that all-important first cry. Soon you’ll be amazed by how much noise she can make! She’s also continuing to pack on a little more weight — as much as half a pound each week until she’s born.
At 39 weeks, your pregnancy is considered full term. Read our explainer on full term pregnancy for all the information you need on what terms like preterm, early term, and late term mean.
How Is Your Baby Positioned When You’re 9 Months Pregnant?
At some point this month, most babies move into a head-down position, if they haven't done so already. This is called a vertex presentation. If your baby is positioned with her buttocks or feet first, this is known as a breech position. If your baby is breech close to your due date, your healthcare provider may attempt to turn her into a head-down position manually; in some cases, you could be offered a cesarean birth if your provider thinks this is the safest option for you and your baby. It’s also possible that your little gymnast may change positions on her own more than once before she’s born. Your provider will be keeping an eye on her positions at your weekly checkups.
How Big Is Your Baby When You’re 9 Months Pregnant?
By the time you give birth, your baby will be about 18 to 20 inches long and weigh 6 to 9 pounds. Read more about the average baby birth weight and what factors can affect it.

9 Months Pregnant: Your Body’s Changes
You might be feeling big, tired, and impatient at this point, and rightfully so! At this stage of pregnancy, your healthcare provider may recommend a screening for GBS (group B streptococci), which are bacteria that can lead to urinary tract infections in moms-to-be, and, on rare occasions, can be passed to the baby as she moves through the birth canal during delivery. If your test is positive, you’ll likely be given an antibiotic during labor to help prevent passing the bacteria to your baby. Cramps or contractions can be signs of labor at nine months pregnant, so it’s important to remember that there’s a difference between Braxton Hicks contractions, which are practice contractions, and the real thing. Here are a few of the main differences you might notice:
If your water breaks, or you notice mucus plug discharge, these are two other signs that your body is getting ready to go into labor.
How Far Along Are You at 9 Months Pregnant?
At nine months pregnant, you’re so close to the end of your third trimester and your pregnancy! You might still be wondering how many weeks nine months pregnant is. There is no simple answer, as the weeks of pregnancy don't fit evenly within nine distinct months. This final month could start anywhere from 33 weeks to 36 weeks and "end" somewhere around 40 weeks with the birth of your baby.
FAQs at a Glance
At this point in pregnancy, your healthcare provider will measure your fundal height, which is the distance between the pubic bone and the top of your uterus. When the fundal height is measured in centimeters, it usually correlates to how far into your pregnancy you are. So, for example, if you're 35 weeks pregnant, it's likely that your fundal height will be about 35 centimeters.
