Period or implantation

chrissy

I’m pretty sure it’s my period but yesterday would have been 12 DpO and today I had a bowel movement and I guess all the pushing brought town some cm and it had blood mixed in . I kept wiping there was nothing ... I also took a q tip and swirled it around just to see if something got on it that way I could tell if it was my period ... but nothing was on it .... ANY THOUGHTS??? I’m leaning more toward the start of my period ...
