So AF was about 3-4 days early and it was a little brown blood at first and the regular blood for 1 day then it went back to brown on the 3rd day. Usually, it last about 6 days so this was weird. I did think it was implantation, but then it was red. I did bleed my first pregnancy but i tested until AF and got a bfn. Not sure what is going on with my body...any one have an idea?
