Did your cycle go back to "normal" following miscarriage?

How typical is it to experience an irregular cycle after mc? I got AF 27 days after induced miscarriage (typical to my 28 day cycles) so I was stoked that body was regulating. Today, on cd19, I think I started AF again. What in the world?! Is this normal? I'm praying my body goes back to normal soon...😢😢😢 How sad...was so excited to start trying again. 
UPDATE: it WASNT AF! Lasted 12 hours (brown then dark red-NOT enough to fill a tampon) and then dwindled out to trace amounts of light pink spotting! Could it have been implantation bleeding? Guess I'll have to wait to find out.
