How long does it take for the depo shot to take effect in your system? Some say 24 hours others say immediately.

my OB says it goes into effect immediately. after my six week check up I got the shot thinking I was gonna have the adiana procedure done. I had unprotected sex with the hubby that night. now that I hear people saying it can take up to 24 hrs for the shot to take effect, I'm starting to wonder if the mild weight gain and bloating isn't just being caused by the shot. especially since I have been feeling I'll off and on. maybe I'm just paranoid but anyone have advice on this? have u known someone to get pregnant like this?

My doctor always told me you were protected after 3 days. I was happy to wait the three days, in my opinion it was worth it to know that I was protected and would not get pregnant. It has been several years since I was on Depo, perhaps things have changed?

That 24 hour thing is not true. It actually starts to take effect as soon as you take the injection, not 24 hours later. It can take awhile for the hormone to leave your system, and that is about 6 months or even longer.

Do whatever your doc says but I was always told use protection for 3 days.
