Answer
Hi Alaina,
I'm a little confused.  The depo shot generally won't bring on your period.  Oct. 18 was 2 months ago, so if you got pregnant around that time your test would certainly be positive now.  Depo will cause some irregular bleeding and eventually no periods for many women.  If your pregnancy test is negative now, I don't think there's a problem.
