Urgent Help for Kayleigh's Puppy Milo

EDIT: Milo is scheduled for surgery tomorrow morning at 8am (10/24/24), he is getting a pin put into his leg and keeping his leg!! The surgery will cost 3k before taxes. And he will need check ups on his leg for probably 2 months afterwards. THANK YOU EVERYONE WHO HELPED.

Hello, my name is Kayleigh. I am 18 years old with a baby on the way, and my 7-month-old puppy just got hit by a car and now has a severely broken tibia and fibula. The vet wants to fix his leg or amputate. I hate to ask for help or money, but I have nothing right now. I don't have a job, and the money I do get doesn't come in until the first of next month, which still won't be able to cover the cost. I'm 17 weeks pregnant and stuck in a jam and scared for my boy. He is the sweetest, most loving boy ever, and it is destroying me to see him like this.

Back story on how it happened: My friend and I were parked at the Purdy Park n Ride for a bit, and my friend left her passenger door open on my car. Milo (my puppy) got out and ran up to a busy road. I tried my best to run after him, and my friend waited by my car. I didn't make it to him in time, and the guy that hit him was going around 45 to 50 mph. The guy thankfully stopped and gave us his card. He was very sweet, but there is only so much the guy can help with, and that was for the fee of the first vet visit.

I feel terrible asking for help. I don't want any hate. I'm scared, very, very scared. I dropped to my knees in the rain and cried with my boy in my arms. He means everything to me, and he is one of the best dogs ever. Anything would help, I really just want my baby to be better. I will answer any questions or anything.
