Belly button piercing ... infected ?

Ka

Does this seem infected on the top hole to you guys ? I've had it for 7 years, and it was doing great until an ultrasound last week. Baby girl was right under my belly button and the tech was digging in pretty enthusiastically around there with the probe. Since then it's been red and sore like this, so I switched over from my normal ring to my maternity one. Do you guys think it's cause for any concern, or just do a few sea salt soaks ?
