Need some cleaning help

Ashley
Ok moms. I'm hoping someone on here can help me. 
We have carpet in our living room. My small dog is not great and has peed on the carpet several times in hidden places. I have tried numerous different cleaning solutions to get the smell out. None of it is working. Does anyone have any suggestions? We were going to put laminate flooring in but the quote we got was almost double what we were expecting. 
Tricks I have tried:
Vinegar and baking soda
Using my carpet cleaner
Natures miracle
vet-pet cleaning solution 
Hydrogen peroxide 
Plain soap and water 
I've gotta do something soon because my pregnant nose can't handle the awful awful smell. Apparently no one else smells it but me but still. I want the smell gone 😭 I'm willing to try any suggestions!
