Belly button piercing infection??

so i just got my belly button pierced on friday (the 23) and i have been doing sea salt soaks for 10 minutes twice a days so far and cleaning it in the showering with none scented aveno body wash and i don’t know if it’s infected or not?? like it’s still tender but it doesn’t hurt? but there is crust around it and i’m not sure if it’s dried blood or dark yellow or green pus? i’m just upset because i’ve been taking good care of it and wearing loose clothes and everything. what should i do or how should i get that crust off? i’m so upset :(
