Depo Provera is a form of injectable birth control where people are seen every 10 to 13 weeks for a repeat injection.
You have stated that your Depo expires on July 3rd, I am unsure how many weeks this is from your last injection as many clinics will book your appointment at 10 weeks so that you have a few weeks of extra time in case anything comes up. You have 13 weeks of protection from when you get your injection.
If you’re having sex and it has been more than 13 weeks I would recommend using a backup method of birth control as it would be possible to get pregnant.
For more information on Depo have a look at Options for Sexual Health information page.
If you have had penis-vaginal sex with no birth control (has been after 13 weeks), it’s possible to get Emergency Contraception to reduce the chance of getting pregnant. Have a look at Options for Sexual Health information page for additional information.
