I'd like to know this too for sure.
I hatched a 10km egg at lvl 12 and I'm almost certain I shoulda waited.
Came out a 709 Magmar

U dun goofed. I hatched a 10km egg at lvl 8 and it was 388 lapras. Ur too low lvl to get high cp

Wish i knew this i wasted so many incense too

Oh garbage. She's up to 5 here in the house. I caught the last 2 though. All like 14 CP though. Weedle and bellsprout.

Curious, what level would you wait till before you use incense/10km eggs now?

For real though. The game is addicting in the sense of you feel like you just need to hit that next progression, whether it's a level up or evolve. The game itself is extremely repetitive and kind of boring if you actually think about it.

Like now I'm just trying to catch my brother and friends in level and that's mainly why I play.

I walked up to the spot and there is literally 30 Adirondack chairs in a circle and as soon as I sit down, I hear "Well the servers are down, time to leave"

I was so mad haha. Thankfully I had my gre book to study while I waited.

So wat lvl i need? Can i stop my egg from hatching?

I made the same mistake

There's no way to stop it

Ill just not walk or drive with it open lol

Maybe only lvl sitting still so as not to hatch your egg until you've lvl'd up? Even that might not work.
Good luck
