I ovulated 3 days ago and for the past 2 days i've been having brown blood just when i wipe. i've never had this before i also had unprotected sex with my partner on ovulation day?

You did not make your question clear enough and you may want to broach your question in a more direct way. The brownish discharge may come from trauma from the sexual encounter or may be implantation bleeding because you set out to have sex to coincide with your ovulation; however it may also be from the other orifices like the anus or the urethra.
