HELP belly button piercing?

so i got it done about a month ago. i clean it with dial antibacterial soap twice a day. and so a sea salt soak once a day. i just got out of the shower (after doing the antibacterial soap) and saw a tinny bit of like a light green puss(i guess im not sure what to call it) it does not hurt. and it is not really red (i went to the place where i got it done last week cause it was a little red, and the girl said its gonna be that way for a while and not to worry) so im just wondering, is the light green puss normal? thanks so much :)
