Need advice.

Erika
Okay ladies. I'm getting married in a week. I'm late for a period.
What does implantation bleeding look/ feel like??
I was ovulating about 2.5 weeks ago but I got a brownish really creamy thing happening when I wiped. Now I'm here 6 days late. 
So please help me. Info overload me. Lol is there a chance I actually could be?!
