Septum Piercing

Krislyn • Hello ♡
For the past few years I have been really wanting to get a septum piercing. The only problem is one parent is against the idea completely, while the other supports it (for my 17th birthday). 
I plan on piercing my own nose, as I have researched a lot about it and realize the main importance to the piercing is sanitizing/keeping it clean. 
I purchased the materials, a 5-pack of the correct size guage needles and a pair of clamp forceps. 
But I was curious if there are any tips in numbing the 'sweet spot' or any opinions on the pain scale?
