Implantation bleeding ?

kashh

Yesterday around 4am( cd23) when I went to the bathroom I wiped and saw this. I’ve never seen this color of blood before. My cycle ranges from 23-27 days, so thinking I must’ve started my period i put a tampon in later in the day around noon so if I did start heavy I didnt bleed thru , but when I took it out hours later there was nothing on it but a small spot of brown.
