The 4th Trimester: What to Expect

Your body is doing enormous work

In the first six weeks your uterus shrinks from roughly the size of a watermelon back toward the size of a pear. Bleeding (lochia) tapers from red to pink to pale over several weeks. Afterpains — cramping while feeding — are your uterus contracting down, and they're often stronger with each subsequent baby. None of this is a sign you're behind. It's the work.

Weeks 1–2: the tender days

Expect soreness, swelling, night sweats as your fluid volume normalizes, and exhaustion that sleep doesn't immediately fix. Your only jobs are rest, food, fluids, and your baby. Sitting up counts as activity. This is the window to accept every concrete offer of help.

Weeks 3–6: finding a rhythm

Bleeding lightens, energy flickers back in patches, and a rhythm starts to appear — then disappears the moment you name it. Baby blues (weepiness, mood swings) affect most new mothers and usually lift within two weeks. Sadness or anxiety that stays past two weeks is not weakness; it's a treatable condition, and it deserves a call.

Weeks 6–12: rebuilding

Around six weeks most people have their postpartum visit — bring written questions, because you will forget them. Clearance for exercise and intimacy is individual, not a date on a calendar. Pelvic floor symptoms (leaking, heaviness, pain) are common but not something you have to live with; they respond well to specialized therapy.

What nobody warns you about

Hair shedding around month three. Feeling touched-out. Crying at commercials. Rage that surprises you. The strange grief of your old life alongside deep love for your new one. All of this is common, and none of it means you're doing it wrong.

When to call

Heavy bleeding (soaking a pad in an hour or clots larger than an egg), a headache that won't lift or vision changes, fever of 100.4°F or higher, chest pain or trouble breathing, a swollen painful calf, or any thought of harming yourself or your baby. Trust your instinct — if something feels wrong, call. You are never bothering anyone.
