Yeah i will take him outside during my work breaks since the outside temps are high

Outside time would be best in this situation. 2 days is a pretty short amount of time, so your friend will be fine.

I broke my bearded dragon uvb lamp and now can only get a new one 2 days from now, will he be ok?
Should i feed him more calcium with D3 during the time he has no UVB maybe even go a couple of minutes outside so he can use the sun? 
Just kinda worried since its a young bearded dragon and want to prevent any chance of him getting mbd
