I had sex 2 days ago and my depo shot ended today. i'm not able to get my shot today.. is there a chance i can get pregnant. i'm really scared ?

Very unlikely timing: There is always a chance of getting pregnant with unprotected sex; however, the depot does not work exactly 3 months and the idea of not getting it every 90 days is taken into account. You are also at a low risk time of pregnancy so the risk of pregnancy just after a missed depot shot is very low. Don't forget about STD's, though, and if you have any sx's of pregnancy you need to check.
