I need some help, I was 4 days late for my period and it shows up but its nothing but dark brown with the occasional pinkish red. It wasn't enough to fill a tampon but more than spotting on a pad, it lasted 5 days. The consistency is different than normaI, I didn't have any clots which is unusual and I haven't experienced any symptoms, pregnancy related or period. I understand that my situation is different than implantation bleeding but i didn't know if there was a possibility it could be.Thank you for any advice I receive.
