Today makes its 15 dpo. My first brown discharge happened at 6 dpo, then again yesterday 14 dpo, and again this morning 15 dpo. I dont have regular periods and brown discharge is out of the ordinary unless its the ending of my period. Took hpt and got bfn. I can only assume its implantation because Im not on any type of birth control and no sign of AF yet. Has anyone gone through the same thing? I want to have a blood test in one week but I am seeking advice or past experiences if anyone can! Thanks in advance!
