It depends what method of birth control you are talking about.

  • Depot medroxyprogesterone (the shot) can take 6–9 months to go back to normal.
  • The pill/patch/ring – in 3 days you go back to normal.
  • The IUD – you can go back to normal within 1 week of removal, possibly sooner.
  • The implant – same as the pill/patch/ring.
