I need serious help. Im literally begging.

So a the weekend after last my cousin asked to borrow my car to take her two kids and some friends to a pic nic for a school thing and her truck couldnt fit everyone. So not thinking anything of it I traded my trail blazer for her truck for the weekend. When we traded back my car was a mess. Food bags every where, empty soda cans, pieces of food and candy all over the seats and floor. Needless to say we had words but I ended up cleaning it all up. Im not super pissed because she had a lot of kids with her and I know that can get out of hand quick or what ever. Any way, a few days later my car started STINKING. Like bad. Like vomit worthy. So i was like ok so i didn’t find something and its been sitting in my hot car. I snooped around and found a half drank coagulated bottle of strawberry milk shoved far up under my driver seat. I threw it away obviously, but it continued to smell. That day I took dawn dish soap and a brush and scrubbed the carpet as far as i could reach and let it dry, then every other day or so ive been putting baking soda on the carpet and then Vacuum it out the next day after work and it still reaks. Im desperate you guys. I need a cure for this stank or im gonna lose it. Im 22 weeks pregnant and my already heightened sense of smell/nausea has taken all it can handle. Ive been getting by with riding the windows down and air freshener spray. But this week its cold and rainy. Idk what to do.
