I got my first depo shot like about a month ago. I got my period days after.. it was OK, a normal period lasted 3-4 days. It went away.. When I never expected I started spotting brown-light red at first I thought it was normal because of my period. Its time that it just doesn't go away. I spot brown but once in awhile normal red blood its weird it stops but once I'm in the bathroom again I'm spotting again... Knowing that its been more than week is really getting me concern.. When ever I have sex I start bleeding again.. I don't know if it's the Depo shot or if I might be pregnant. I've been craving food a lot. And my tummy feels blotted the whole day. Please help...
