I'm Having An Nose Piercing Bump Over A Month Now,

I'm having an nose piercing bump over a month now, and as the time goes it eventually gets bigger and smaller and it always bursts out with blood, as being an 13 year old school girl that's embarrassing when someone asks you what's that on your nose. I have recently purchased a skin cream called soframycin and my family suggested it. Can you please tell me how many times I have to apply it and how?
