Your Body After Baby: What to Expect in the Fourth Trimester

November 11, 2025

It’s easy to find information about what to expect during pregnancy, they even wrote a book about it. But what about after the birth of your baby — what’s often called the fourth trimester? 


This critical period often gets overlooked, even though it’s filled with physical and emotional changes that deserve as much attention.


At Obstetricians & Gynecologists, PC, in Hastings and Grand Island, Nebraska, our team supports you through every stage of motherhood, from pregnancy to postpartum recovery. Here’s what you can expect from your body and mind in the fourth trimester, plus tips to help you heal and adjust.


What is the fourth trimester?

The fourth trimester refers to the first 12 weeks after delivery of your baby. Though not as widely discussed as the 40 weeks of pregnancy, this stage is equally important for your health and well-being.


During this time, your body and mind undergo immense physical, emotional, and social adjustments. You’re recovering from childbirth, adapting to a new sleep schedule, and learning how to care for a newborn — all while your hormones are shifting. 


It’s no wonder many new moms feel exhausted, overwhelmed, and unsure of what’s normal.


Because of these significant changes, we view the fourth trimester as a vital part of your pregnancy care, not as an afterthought. 


Your body after baby

You may find it surprising that your belly doesn’t return to its pre-pregnancy size right away. In fact, you may still look pregnant for a while, and that’s completely normal. 


Your uterus, abdominal muscles, ligaments, and skin all stretch during pregnancy to make room for the growing baby. While your uterus shrinks after birth, it can take about six weeks to return to its pre-pregnancy size. Cramping is common as the uterus contracts; it’s sometimes so intense that it catches you off guard. 


Vaginal discharge, called lochia, is another part of the recovery process. This discharge consists of blood, mucus, and tissue shed from your healing uterus, and it can last several weeks.


Pregnancy and childbirth can also weaken your pelvic floor — a group of muscles that support the pelvic organs and help control bowel and bladder function. Weakening of these muscles can lead to incontinence (urine leakage) or a feeling of pressure due to pelvic prolapse.


Though you may find your body after baby worrisome, all of these symptoms and conditions are treatable.


Emotional and mental adjustments 

As your body is healing, your emotions are recalibrating. Many new moms describe feeling like they’re on an emotional roller coaster, happy one minute, tearful the next. This is largely due to the sudden drop in pregnancy hormones right after birth.


Most women experience the baby blues during the first week or two after delivery, which causes feelings of sadness, anxiety, and irritability. These feelings usually fade within a couple of weeks. 


However, if your mood doesn’t improve or you find it hard to care for yourself or your baby, you may have postpartum depression, a common and treatable mental health condition. 


At Obstetricians & Gynecologists, our team takes your emotional well-being during the fourth trimester seriously and checks in on you regularly so you get the support you need.


What to expect from postpartum care

While postpartum visits are less frequent than prenatal care appointments, they’re still important. Typically, we schedule your first visit about three weeks after birth, followed by a comprehensive physical exam before the end of the 12-week period. 


If you had a Cesarean section or vaginal tearing, we schedule additional visits to monitor your healing. 


Once you complete your postpartum recovery, we transition you to well-woman visits so we can continue to support and manage your long-term health.


The fourth trimester is as important as the first three, and you don’t have to navigate it alone. We provide comprehensive women’s healthcare throughout every stage, from prenatal to postpartum and beyond.
