Is my helix piercing infected?

my helix peircing just started hurting; i pierced it myself about 3 weeks ago and it hasnt hurt until today, DONT SAY IM STUPID, I DID 4 OTHER PIERCINGS MYSELF AND THEY NEEEVEEERRR GOT INFECTED. anyways, i took the helix out yesterday, washed my ear, disinfected the earring and then stuck it back in but half way in i discovered my ear was bleeding; then i realized that the BACK of the ear is a little swollen, should i take the earring out or leave it in? and is this normal, or is it infected? o:
