Its definately not good to worry about it-I find that mine bleeds as soon as I get stressed.
I'm sure you've got nothing to worry about and it should heal up fine-statistics are on your side!
The things to look out for are-more pain than usual, feeling like you've got flu, you know that tired achy feeling?
Watch out for any pus ,
or white streaks on skin tag(if you have one)
These are just precautions, try not to worry too much, I'm sure you'll be fine!
