Twelve weeks that ask a lot of you. Here is what is normal, what helps, and when to pick up the phone.

In short

The postpartum period, often called the fourth trimester, covers roughly the first 12 weeks after birth. Bleeding usually settles by 6 to 8 weeks, a first check with your care team is recommended within 3 weeks, and a full postpartum visit by 12 weeks. Mood dips in the first two weeks are common; anything stronger or longer deserves a conversation with your midwife or doctor.

What the fourth trimester really looks like

The weeks after birth are not a return to "before". They are a stage of their own, with a body that is healing, hormones that are resetting, and a baby who feeds around the clock. ACOG describes postpartum care as an ongoing process rather than a single appointment, built around your own needs.

Time after birth	What is usually happening	What to keep an eye on
First 24 to 72 hours	Heavy bleeding (lochia), cramps when feeding, colostrum, checks of temperature, pulse and blood pressure	Bleeding that soaks pads quickly, fever, feeling faint
Days 3 to 14	Milk often comes in around days 2 to 4, bleeding lightens and turns brownish, the baby blues may come and go	Low mood that deepens instead of lifting after 2 weeks
Weeks 2 to 6	Stitches heal and usually dissolve, energy slowly returns, short walks feel good	A wound that is red, hot or smells unpleasant
Weeks 6 to 12	Bleeding has usually stopped by 6 to 8 weeks, postnatal check, gradual return to exercise	Leaking urine, a heavy feeling in the pelvis, a tummy gap that is not closing

Your care calendar

Within 3 weeks: ACOG recommends contact with your obstetrician or midwife, by visit or phone.
6 to 8 weeks (UK): the NHS postnatal check with your GP covers healing, mood, contraception and, if needed, blood pressure.
By 12 weeks (US): a comprehensive visit covering mood, feeding, sleep, sex and contraception, physical recovery and any chronic condition.

Write your questions down as they come, in your phone or on paper. At the check you will be tired, and the list does the remembering for you.

Is this normal? When to call

Tiredness, tears in the first two weeks, cramps while feeding and bleeding that slowly fades are all normal. Some signs are not. The CDC lists urgent maternal warning signs that can appear up to a year after delivery. Seek care straight away if you notice:

a headache that does not go away or comes with blurred vision or dizziness;
fainting, dizziness or gaps in memory;
a fever of 100.4 °F (38 °C) or higher;
trouble breathing, chest pain or a fast or irregular heartbeat;
heavy bleeding, large clots or foul-smelling discharge;
severe swelling, redness or pain in a leg or arm;
severe belly pain that does not go away, or overwhelming tiredness;
thoughts of harming yourself or your baby.

When to call. Emergency: 911 (US) or 999 (UK). Not sure? Call your maternity unit, your OB-GYN or your midwife, or NHS 111 in the UK. Say you gave birth recently, and when.

Questions parents ask

How long is the postpartum period?

Medically it is often counted as the first 6 to 12 weeks after birth, and ACOG recommends a comprehensive postpartum visit no later than 12 weeks. Some health problems linked to pregnancy can still appear up to a year after delivery, so mention a recent birth whenever you see a clinician that year.

When is the postnatal check?

In the UK the NHS offers a postnatal check 6 to 8 weeks after the birth. In the US, ACOG recommends contact with your obstetric provider within the first 3 weeks, then ongoing care ending with a full visit by 12 weeks.

What postpartum symptoms are an emergency?

Sudden very heavy bleeding, chest pain, trouble breathing, a severe headache with vision changes, or thoughts of harming yourself or your baby. Call 911 in the US or 999 in the UK.
