Two Periods, One Month.

Lacy • 19. Married. In love. Ready and waiting to become a mommy. :)
Has anyone else had two periods in the same month? I started around the 11th of this month and finished around the 15th/16th of this month and I started back the 24th (a few days ago)... Can anyone give me a little insite on this?? This has never happened before. Thank you!!!
