Is two periods in one month a postpartum thing??

Am I really having a 2nd period this month!? This is crazy! 😩 I always had very regular periods buuuut... had my 1st baby 13 months ago, I'm still breastfeeding on demand and my period started back at 11 months pp.

The first two cycles were 30 days apart (my normal) the 3rd cycle came late at 33 days (May 17th). Currently I'm on day 3 of another?? It started 9 days after the other ended. Seriously?!?

Has something like this ever happen to any other mamas? Could it be my hormones are still regulating due to nursing??
