Hey everyone! I'm definitely scared right now.
OK so I was waiting to conceive until I was 20 something.
But now I'm confused. Because I recently got a depo provera shot and I'm unsure whether it worked

see, I first got depo a while back, and then stopped to explore other birth control methods. During the 2 months I was off it (or about that amount of time), I only had 1 period. However, I was tested for pregnancy, but nothing came up.
Now, I'm on depo again, but they gave me the shot when I wasn't menstruating.
SO IM CONFUSED: Did the shot work? Because I wasnt bleeding when they gave me the shot! ! !
Because I "did it" about 28 or 29 days after the shot.
I'm so scared, could I be pregnant? Or could I have been pregnant before the shot, and I still am pregnant?
I'm worried because I've been spotting, and sometimes bleeding.
Worried!
Thanks --- sorry for TMI !
