Am I allergic to my belly on rings ?

I got the triple piercing on my belly on in Feb. then later I got my fourth done in March. One was pushed out. So I took the other side out cause it was pointless. Then the other two healed all the way on the outside abut I don't know about the inside. They're still the original rings they pierced me with. And then one day I woke up and one piercing was red, swollen, and it hurt, puss was coming out. But it wasn't green so I know its not an infection. Then the other one got like that to.
