New Owner Here!! how long can my bearded dragon go without UVB?

This is Ellery!! I accidentally cracked her UVB coil light last night so I immediately checked every store near me to see if they had any UVB linear lights but smh no store has any in stock, there’s one store that does but it’s like 2 hours away. My only option left was Amazon but it arrives this Saturday. What I’m worried about is Ellery being without it for 4 days. I’m kinda freaking out cause I don’t want her to develop MBD. Will Ellery be okay? I just want to do everything to keep my new kid healthy and happy:(
