Seven months pregnant covers weeks 28 through 31 of pregnancy. This puts you right at the start of the third trimester, with roughly 9 to 12 weeks left until your due date.
If the math feels confusing, you’re not alone. Pregnancy is 40 weeks long, which actually works out to about 10 months, not nine. That’s because the countdown starts on the first day of your last menstrual period, not from conception. So the familiar “nine months” shorthand doesn’t map neatly onto the weekly timeline your doctor uses.
Why Weeks and Months Don’t Line Up
Most calendar months are 30 or 31 days, slightly longer than four weeks (28 days). Over the course of pregnancy, that extra day or two per month adds up. The full 40-week timeline equals 280 days, or just over 10 calendar months from the start of your last period. This is why your provider tracks everything by week rather than month. Weeks give a more precise picture of where you and your baby are in development.
Different sources slice the months slightly differently, which can add to the confusion. The important number is your gestational week. If someone asks how far along you are and you say “29 weeks,” that communicates more to a healthcare provider than “seven months” ever could.
What’s Happening With Your Baby
At 28 weeks, your baby weighs about 2.25 pounds and measures roughly 10 inches from head to tailbone. The eyelids can partially open for the first time. The central nervous system has matured enough to regulate body temperature and control rhythmic breathing movements, which can show up on ultrasound even though the lungs won’t breathe air for weeks.
Over the next few weeks, your baby will gain weight rapidly, packing on fat that helps with temperature regulation after birth. Brain development is accelerating, and the bones are hardening, though the skull stays flexible to make delivery possible.
What Month 7 Feels Like
Your belly is large enough now to shift your center of gravity, which can throw off your balance. Many women notice Braxton Hicks contractions becoming more frequent around this time. These practice contractions feel like a tightening across your abdomen. They tend to show up in the afternoon or evening, especially after physical activity or sex, and they come and go irregularly. They’re normal, but if you’re getting more than five or six in an hour and they’re getting steadily stronger, that’s worth a call to your provider.
You can expect to gain about a pound per week during month seven. As the baby grows, pressure on your bladder increases, sending you to the bathroom more often. Some women also start feeling mild pelvic pressure as the baby settles lower.
Kick Counting Starts Now
By 28 weeks, you should have a general sense of when your baby is active and when they’re quiet. This is the point where many providers recommend starting formal kick counts. There are two common approaches: count how many movements you feel in one hour, or time how long it takes to feel 10 movements. Either way, the goal is to establish a baseline so you’d notice if something changed. Pick a time of day when your baby is usually active, sit or lie down, and pay attention.
Screenings Around This Time
If you haven’t already had your glucose screening for gestational diabetes, it typically happens between weeks 24 and 28. This test involves drinking a sugary solution and having your blood drawn afterward to see how your body processes the sugar. Some women with higher risk factors are screened earlier. By month seven, this test is usually behind you, and your prenatal visits start becoming more frequent as you move through the third trimester.
If Your Baby Were Born at 28 Weeks
Reaching 28 weeks is a significant milestone for viability. Babies born at this point have a survival rate between 80 and 90 percent, and only about a 10 percent chance of long-term health problems. That said, every additional week in the womb improves outcomes. Babies born this early typically need time in a neonatal intensive care unit to support breathing, feeding, and temperature regulation while their organs finish maturing.
The Weeks Ahead
Month eight (roughly weeks 32 through 35) brings stronger contractions and increasing shortness of breath as the baby crowds your lungs and stomach. By month nine (weeks 36 through 40), the baby usually drops lower into your pelvis. That relieves the pressure on your lungs but puts more weight on your bladder. Weight gain typically slows or stops in the final weeks, and some women lose a pound or two before delivery.
From here, the remaining 9 to 12 weeks tend to feel longer than the rest of pregnancy combined. Your body is doing its heaviest work, and your baby is doing most of their growing. The finish line is closer than it looks on the calendar.
