How long after getting the depo until it works where me and my hubby don't have to where a condom

It is usually recommended that you use a second form of protection for about a month. However, I believe it is only a couple of weeks with the depo shot. Remember too that no form of birth control is 100% effective.

I have a classmate due in November who got pregnant with depo. This is a rarity, but it is still possible.

With the Depo shot I was always told that I needed extra protection for the first two weeks of starting the shot and if you are ever late with getting your shot again then its another two weeks then too, so try to be on time.
