worried about period

okay guys...this is a problem that has been bothering me over the past few days

2 days ago - I got my period (or what I think is my period) but it was much lighter than usual, and more brown/pink...and only minor spotting and then more when I wiped. I have intense stomach and abdomen cramps and I have been feeling ill too.

I am 17 years old and a virgin.

Now that I have heard of implantation bleeding, I am starting to worry I might be pregnant.About 11 days ago, I went to a club and consumed a large amount of alcohol. Therefore, I do not recall every single moment of my time at the club. I do remember how I left, and how I got there.  I also remember certain conversations, and I have a lot of pictures on my camera in which I look fine. I went there with 10 other friends I know really wellI. I also remember who I danced with and and i cannot recall meeting any guy. . However, it seems that there is one hour I really don't remember anything about. Could I have been date raped? Or simply had sex and not remember because of my alcohol use?


I know this all sounds crazy....but I am prone to worrying and if one of you could help me out - please do!
