So I got the depo shot a week before my period was suppose to start... I've been having alot of pregnancy symptoms and now my period has not showed up on schedule... Bf is stressed and my anxiety is high I've had a negative pregnancy test so I'm thinking it's just the shot that has my body off... However the only thing that has me second guessing that is because when I was a teen on it, it took a few shots of not half a yr before it ceased a period I've never heard of depo working this quick to stop a period. Does any one having any experience with this?
