Belly Piercing and Nose Piercing?

Well you see I'm 14 and I want to get my belly pierced and my nose pierced. But the problem is that my skin gets infected real easily. For instance I have two ear pierces for each ear. And for those I had to really take good care of them. Of course like a week after i got it done it got infected and pus came out. But my mom took the fake earring out and put some real ones on and then she put vaseline along wit some medicine oil. And now it's good but i WOnder what's going to happen if I get my nose and belly pierced.
