The fourth trimester, and what recovery actually involves

Postnatal care in most countries is built around a single check at around six weeks, after which the pregnancy is considered concluded and attention moves to the baby.

Six weeks is roughly when the uterus has returned to its pre-pregnancy size. It is not when recovery is finished. Abdominal wall function, pelvic floor function, connective tissue remodelling, hair cycling, hormonal stabilisation and — if breastfeeding — an entirely different hormonal state all run on much longer timescales, often a year or more.

What is actually happening

Weeks 0-6. Lochia — bleeding that changes from red to brown to yellow-white — typically lasts four to six weeks. The uterus contracts back, with afterpains that are worse with each subsequent baby and worse during feeding. Perineal or caesarean wounds heal. Night sweats are common as fluid is offloaded.

Weeks 6-12. Fatigue that has less to do with sleep than people assume. Hair shedding begins around three months — telogen effluvium, caused by the synchronised hair cycles of pregnancy ending together. It looks alarming and it recovers over six to twelve months.

Months 3-12. Abdominal wall function, particularly with diastasis recti, continues to improve with appropriate loading. Pelvic floor strength continues improving with training. Joint laxity from relaxin resolves gradually. If breastfeeding, oestrogen stays low, which has consequences discussed below.

The things that are common and should not be accepted

This is the important section, because a great deal gets normalised.

Urinary incontinence. Leaking when you cough, sneeze, laugh or run is common in the early weeks and is not something to live with past that. It is treatable, usually with pelvic floor muscle training supervised by a physiotherapist, and outcomes are better the earlier it is addressed. In France and several other countries, postnatal pelvic floor physiotherapy is routine; elsewhere you often have to ask. The pelvic floor is a muscle group covers what training actually involves.

Prolapse symptoms — heaviness, dragging, a sensation of something coming down. Common, under-reported, and treatable.

Pain with sex. Extremely common in the first months and very often persistent because nobody asks. Low oestrogen while breastfeeding causes vaginal dryness and tissue thinning that responds well to lubricant and, where needed, topical oestrogen — which is safe in breastfeeding. Scar tissue from tearing responds to physiotherapy. Why sex hurts covers the full list.

Faecal incontinence or urgency. Under-reported because of shame, and a marker of possible obstetric anal sphincter injury. It requires specialist assessment, not endurance.

Back and pelvic girdle pain persisting past a few months.

Fatigue that does not track with sleep. Postpartum iron deficiency is common, especially after significant blood loss, and postpartum thyroiditis affects a meaningful minority — often a transient hyperthyroid phase followed by a hypothyroid one, both easily mistaken for normal new-parent exhaustion. Both are worth testing for. Fatigue that sleep doesn't fix.

Returning to exercise

The common advice is "wait six weeks", which is a clearance for medical safety rather than a training plan.

A more useful framing: walking and gentle breath-and-core work can begin early. Progressive loading — resistance training — can start once cleared and should be built gradually. Impact activity such as running warrants pelvic floor assessment first, and many physiotherapists suggest around three months as a reasonable earliest point for most people, guided by symptoms rather than the calendar.

The signals to stop and get assessed: leaking, heaviness or dragging, pain, or doming of the abdomen under load.

Strength training is not something to be cautious of here — it is among the most useful things for recovering function, bone and metabolic health. Strength training does more for women than any other exercise.

Your cycle comes back on its own schedule

Without breastfeeding, periods typically return within six to twelve weeks. With exclusive breastfeeding, it can be many months, and the first ovulation happens before the first period — which is why "I haven't had a period yet" is not contraception.

Early returning cycles are often irregular or anovulatory. The first cycles back are often irregular for the same reason they are after stopping contraception — ovulation has to re-establish. Coming off hormonal birth control covers that process.

What a good postnatal check should cover

Beyond blood pressure and the wound: continence, prolapse symptoms, sexual function, mood and anxiety, sleep, contraception, thyroid and iron if there are symptoms, and a clear plan for pelvic floor physiotherapy if anything is off.

If your six-week appointment lasted eight minutes and covered contraception and nothing else, that is not unusual and it is worth booking a longer one for the rest. How to prepare for a ten-minute appointment has the approach.

Track it, because the timeline is long and the changes are slow

Recovery over a year is hard to perceive from inside. Things improve gradually enough that you cannot tell whether they are improving, which is demoralising and also makes it hard to know when to escalate.

A simple weekly note — pain, leaking, mood, energy, sleep, what you managed physically — turns that into something visible. It is also what makes a referral conversation concrete: "still leaking on impact at five months despite daily exercises" gets a physiotherapy referral in a way that "I'm still not quite right" does not.

Naked is built to hold that record with minimal effort, alongside the mental health side, which is at least as important and at least as easy to lose track of.
