Period?

So I’m EBF mommy. And I got my period early. I had my daughter on 11/15/17.....

On Sunday I had bad cramps but I thought it was from eating to much on Christmas eve. Because next think you know it. I’m in the toilet for a good 7mins. I seen a little red. But I thought it was from sh*t to much, so it probably from my a*hole lol. Anyways Christmas morning I felt the cramps again. I’m like “Oh Lord, here I go again”. But I just pee and when I wipe I seen lot of blood, like when you first get your period... I’m like okay I got my period, but then I realized I’m only BF, so how?........ has anyone else go their period yet?
