It can take a long time after your last Depo shot for your fertility to return. The average amount of time it takes someone to get pregnant after stopping Depo is 9 to 10 months – this means about half of people who stop Depo will get pregnant within 10 months. By 18 months after the last shot, about 90% of people will get pregnant [https://managingcontraception.com/after-taking-only-two-depo-provera-shots-how-long-will-it-take-for-me-to-become-pregnant-30315/ and https://www.accessdata.fda.gov/drugsatfda_docs/label/2010/020246s036lbl.pdf ]. If someone wants to use Depo and knows she would like to be pregnant within a year or so, Depo may not be the best method (especially for people over age 35). If you are planning to conceive in the near future and have used Depo, we encourage you to talk to your provider about other methods of birth control, or when to stop using Depo.
