How effective is the depo birth control shot for y'all ?

If you think you might be pregnant, then it wouldn't be a bad idea, but I have heard it is REALLY rare for it to happen!

So I should take plan b ? @jessica415

My mom also got pregnant with me while she was on depo

Not very effective for me, considering I'm 38 weeks pregnant with my son who was conceived about a month into the 3 month cycle for the depo shot lol

I've seen a few depo babies.
