don't worry about it. if anything looks out of the ordinary, go see your piercer.

Signs of infection include deep redness, serious pain, swelling, heat, and pus. Remember that healing piercings release lymph fluid, which is normal and not pus. If you have clear, yellowish crust, that's normal. Opaque yellow or greenish discharge is bad, especially if it smells bad. So make sure you're using saline soaks and gentle soap, and keep up your aftercare for the entire healing time. Navels are known to heal slowly, so don't be surprised if it needs aftercare for up to a year. If you suspect infection, do not remove the jewelry, because that lets the infection have a drainage path. Pain and tenderness are normal. Lymph crust is normal, but don't pick or twist your jewelry to remove it. Wait until after washing or soaking to wipe it away. A little blood is normal for a few days afterward, but after a week or two, most piercings won't bleed unless injured. If you get sick, your piercing may backslide and feel more sore, or you may notice swelling. Often a sore piercing will let you know you've got a cold coming on. Piercings heal from the outside in, so don't assume that it is healed when it looks healed. Continue your aftercare for 4 weeks after there's no tenderness or crust. With a navel, I might go more than 4 weeks. They're often fussy and should be babied as long as possible. Also, itching means you're healing, although it may also mean your saline soaks are too salty if your skin looks dry. Scratching the skin a few inches away from the piercing sometimes helps relive the itch, and make sure to rinse your piercing with clean water after saline soaks.

wow thank you so much that was really helpful information! cheers!
