Implantation Bleeding

Mia

i have irregular periods because of my thyroid, i also have a hard time tracking my ovulation but I've been trying to conceive for a while now, anyways I've been having brown discharge and blood, is it my period? It's not pad full of blood but it's a few drops of red blood and brown for less than a day now I'm not having any just brown when I wipe it lasted for about 1 day at like 5 so it wasn't all day!
