I have been off the depro shot for 6months and finally last week I thought I was going to have my period. I had a brownish discharge and no period has come is that normal or could I be pregnant

I don't know much about the depro shot but your body could be reacting to the shot. Hormones are every where right now. There is something called implantation bleeding that happens about a week before your period would start. Of course I believe it is rare to have but some women get it. To be on the safe side buy a HPT and test.
