Hi , My Boyfriend And I Proceeded To Have A

Hi , My boyfriend and I proceeded to have a little bit too much fun. I now have a hickey on my chest and used a few attempts to get it away due to the fact that I'm going swimming with my mother tomorrow and she has always found them unacceptable. It now hurts due to applying ice , using suction and circular motions , toothpaste on , and Neosporin. Is this normal and will it go away fast ? Or should I get it checked out? Could it be from how I treated it ? Should I just let it stay due to it being a bruise ?
