STUPID EAR PIERCINGS WONT HEAL!!!!!

Hi, everyone!! The picture with this post shows my ear piercings that I got done earlier this year on February 18th, 2019. The new piercings are my second ear lobe piercing, and the cartilage. The other side is just the second ear lobe piercing. I got these piercings done at Claire’s, with a gun, and YES I know that was stupid, but it was a spur of the moment thing, and everything was fine afterwards. They told me to clean the piercings twice daily, and the cartilage would take 12 weeks to heal, while the ear lobes would take 6 weeks. So during this time, even though I consistently cleaned my piercings, my cartilage got super infected, which ended up with me having to take some pretty strong antibiotics. It was super painful, but it healed. I haven’t taken the cartilage piercing out to change it yet, and I don’t intend to change it for a pretty long time. Now, with my second ear lobe piercings, I took them out at the 7 week mark to change them. I used sterling silver jewelry, cleaned them, and they got infected. I changed those piercings twice. Can anyone tell me WHY it’s June 14th, almost FOUR MONTHS LATER, and all 3 of these piercings are still getting slightly infected and giving me issues?!?!?! I got them because I want them to be cute, and I can’t even change them now because of the pain and infection problems.
