Ears punched at 0g, chose wrong colour.

I chose the wrong colour glass plugs today after I got my ears punched. I ordered the same ones but in a different colour, would it be ok for a quick change over in two days when they arrive?

Edit: Guys I made a mistake, punched to 6mm, stretched to 8mm. Sorry sorry sorry. Made a lot of you guys freak out and while it made me laugh, I thought I’d come and correct it.

Thanks for your advice people, appreciate it. I’ve decided I’m going to ask my piercer what to do, apparently they can fall out sometimes anyways due to sleeping etc so I figured, if they can fall out for a couple of seconds, they can probably be swapped out right? Idk. Thank you anyways guys, I’ll take every precaution before making an informed choice.
