Bleeding, 3 months after giving birth....

[loisstella]

Okay, I know TMI, but heres the data:

Had a heavy period after 6 weeks of lochia, had the injection pill.
3,5 weeks later I had an 18 day period! now, 4 days later I'm bleeding (a little bit) again.
Is this normal??? Should I get this checked out?
Anyone??

Does the injection not start out like this ( lots of bleeding for the first few months) and then settle down? Hope more expert opinion will be along soon.
