…Is there a possibility that I might be pregnant?
If you this was the first time you have taken the Depo shot or you were restarting the method (you were off of it for a while and just decided to start back up), it will not be effective for the first week.
When someone starts a new hormonal method of birth control (like the Depo shot), they need to use a back up method (like condoms or practicing abstinence) for one week before that method will be effective. After that first week, the hormones will be integrated into the body and can help prevent pregnancy up to 99% when taken correctly.
If this is the case and you were just starting on Depo, you will not be protected from pregnancy for the first week. This means that if you had unprotected sex a few days after your first injection, you are at risk of pregnancy. If you are not wanting to be pregnant, it may be a good idea to pick up emergency contraception.
If you had been on the Depo before and had just gotten your next shot (if you were continuing on with the 3 month schedule), you don’t need to wait one week after each shot for it to be effective.
The one-week grace period is only applicable to people who are starting a new method.
