## TLDR

- Night sweats, swelling and lots of peeing are common for the first few weeks as your body clears extra fluid.
- Hair often sheds heavily from about 2-4 months and usually returns to normal by a year; aim to regain your pre-pregnancy weight slowly over 6-12 months.
- Contact your provider soon for a red, swollen, painful leg or fever with breast pain; call 911 for chest pain or trouble breathing.

## Your belly and uterus

- Right after birth most people still look a few months pregnant. The uterus shrinks back to near its
  usual size by about 6 weeks; afterpains during feeds are part of that.
- The skin and muscles take longer, often many months. A belly that stays soft or rounded is normal.
  See the pelvic floor guide for belly separation.

## Night sweats and swelling

- Drenching sweats, especially at night, are common for the first few weeks as hormones drop and the
  body clears extra fluid. Sleep on a towel, keep a spare shirt nearby and drink water.
- Swelling in the feet and legs can get worse for a few days after birth, then fades over a week or
  two. Put your feet up and walk a little.
- You'll pee a lot in the first days for the same reason.

## Hair loss

- Pregnancy hormones keep hair in its growing phase. After birth, lots of it sheds at once, usually
  starting around 2-4 months and peaking around 4 months.
- It can look alarming (clumps in the shower, thinner temples) but is temporary. Hair usually returns
  to normal fullness by about a year.
- Gentle care helps: a volumizing shampoo, a looser hairstyle, a soft brush, an iron-rich diet.
- Shedding that lasts past a year, or comes with exhaustion, feeling hot or cold, a racing heart or
  big weight changes, is worth a check for thyroid problems or low iron.

## Weight

- Many people lose about 10-13 lb (4.5-6 kg) at birth and more in the first weeks as fluid goes.
- After that, slow and steady is best. Getting back toward your pre-pregnancy weight over 6-12
  months is a reasonable goal, and some bodies settle somewhere new.
- Breastfeeding burns energy but also makes many people hungry. Gentle, gradual loss (about
  1 lb / 0.5 kg a week, once feeding is going well) doesn't usually affect milk supply. Crash diets
  can.
- See the postpartum nutrition guide.

## Skin

- Stretch marks fade from red or purple to silver over months. Creams don't erase them; time does
  most of the work.
- The dark line on the belly and darker patches on the face (melasma) usually fade within a year.
  Sunscreen and a hat help.
- Acne, dry skin and skin tags can come and go with hormones.

## Other surprises

- Periods: may return within 6-12 weeks if you're not breastfeeding, and much later if you are.
  You can get pregnant before the first period.
- Feet can stay half a size bigger. Wrists and thumbs can ache from lifting the baby.
- Breasts change size and shape with feeding and again after weaning.
- Feelings about your body can swing. Your body did something big; give it the same patience you'd
  give a friend.

## When to check in

- Mention at your postpartum visit or a later checkup: hair loss past a year, feeling unusually
  tired, shaky or low, or patches of skin or moles that change.
- Contact your provider soon for a red, swollen, painful leg or fever with breast pain. If you have
  chest pain or trouble breathing, call 911.
