If I got the Depo Shot on Wednesday when I wasn’t on my period & had unprotected sex Monday……..

…….is there a chance I could be pregnant? & are the chances high?

Great question.

It is important to say that pregnancy is possible whenever sperm comes into contact with the vagina.

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, regardless of where they are at in their cycle when they get the shot.

After that first week, the hormones will be integrated into the body and can help prevent pregnancy up to 99% (even if ejaculation occurs in the vagina) when taken correctly. In order for the Depo Shot to be effective, a person needs to get the shot every 3 months.

Since the Depo Shot was not effective yet, and unprotected sex did happen, there is a chance of pregnancy.

Emergency Contraception is an option if pregnancy is not desired. Emergency Contraception contains a high level of progesterone.  This spike of progesterone in the body can prevent ovulation, or keep the egg from being released from the ovary. It is important to take Emergency Contraception as soon as possible after someone thinks pregnancy could have occurred. Emergency Contraception doesn’t work if the person has already ovulated. Also, someone can take Emergency Contraception up to 5 days after pregnancy might have occurred.
