What happens to your body after birth?

By Victoria Shaw, NMC registered midwife. Last reviewed October 2026.

Short answerAfter birth you will bleed, heavily at first, while your womb shrinks and heals. This is called lochia and the NHS says it usually stops after 6 to 8 weeks, though it can last longer. Leaking when you cough, sneeze or laugh is also common, and it is something you can get help with.

How long will I bleed after birth?

You will bleed, heavily at first. It's called lochia. It comes from your womb shrinking back down to about the size of your fist and healing where the placenta was attached. Some days will be lighter and some heavier, and that fluctuation is normal. The NHS says it usually stops after 6 to 8 weeks, but it can last longer.

When should I get help with bleeding?

If you are ever worried about the amount, contact your maternity team. The NHS advises calling 999 if the bleeding is sudden and very heavy, or if you feel faint, dizzy or notice your heart pounding.

Is it normal to leak after birth?

Leaking when you cough, sneeze or laugh is very common after birth. Common doesn't mean you have to put up with it. Pelvic floor exercises help strengthen the muscles that pregnancy and birth weaken, and if you are still leaking, ask your GP about a referral to a pelvic health physiotherapist.
