Implantation

Leann

How soon after implantation will a hpt show positive? I have pcos, so I'm not exactly sure on my cycle since I might have had 2 LH surges. Last night when I wiped there was a slight brownish tinge and then a little later there was some pink. I thought maybe I was going to start my period today but nothing else has happened. I did have mild cramps, a spike in temp and acne yesterday so I'm thinking it was implantation.
