Help! Belly button piercing

Emma
So i just got my belly button pierced like last week, and i've been cleaning it and taking very good care of it but today when i was getting in the shower i noticed that there was like a yellow bruise around the bottom half (i'm not sure if it's a bruise) And i have no clue what it is, or what to do! if anyone has any information on what it could be please comment or inbox me because i'm very concerned (the first is today and the second is when i got it done )
