help!

So I decided because I couldn't sleep I would pull out the wax and finally wax the downstairs area. Well I got halfway through and have noticed it's bruising/hickey like marking me.. this is the first time I have waxed down there so I need advice. Is this normal? Should I be considered? I have stopped haven't finished. Also I have had and waxed my own legs before and this never happened idk if it's because it's more sensitive skin or what. Comments and advice would be great!
