I'm still fully b/fing and I got my first period when Cody was 11 mths old, it was also slightly like you decribed, I believe that you have nothing to worry about, it's just your body getting back into a normal routine, if you can call it that.

Have you considered talking to someone about your birth experience, so that you can get all your fears and emotions out instead of it replaying in your head. I hope that your are ok and I'm sending you big hugs.

hugs xoxo
