Stretching both???

So, this is what i’ve got. The plug is 0g, the second hole was just done today. I plan on stretching past a 0g (currently planning to go to 1/2 inch, but might go bigger), and am wondering if the new hole will effect anything?? They said they left room for stretching and i have bad social anxiety so i didn’t ask any further 😅 Also, what about stretching the new hole? Obviously it’s healing rn, i wouldn’t stretch it for at LEAST like a year. But like, what’s usually the biggest you can go? What all should i know?

I plan on going to a tattoo shop at some point and asking all this. This new piercing was a very sudden, in-the-moment decision so it was done in a stand thing at a mall, with a gun 😂😅
