Hello okay so here goes some info

Last Depo Shot Dec 2009

NOT ON ANY B Control

Sex on and off since then

Last intercourse March 25th 2011

My periods are typically normal every 28days and last for 3-4days
Now this month

I was suppose to get my period April 1st But i got it March 31 looked normal
Flow changed pad three times and then came April 1st and it stopped for a few hours and then noticed spotting but only when i wipe nothing on my liners. april 1 and 2nd.

Oh yeah has anyone had like black spots looked red at first but when i noticed my pad had like lots of black spots and would notice fairly quickly

Does anyone know or have any ideas on whats going on. or same experiences? I have been trying to get pregnant, and when i got my period i lost little hope but this cycle is very ODD
