I want you to avoid the mistake I made with 1-2 gallons of water. Go ahead and pull the trim plastic now and lift up the carpet and underpad. If you don't, it WILL mold and stink. I just dried mine out, but I made the mistake of thinking the hot summer sun and blowing a fan on it every night would be enough. Fast forward a week or two and the smell is unbearable and the carpet is still noticeably moist in the afternoons (felt dry in the morning!). The pad holds in a lot of moisture and without pulling it all up and letting it dry from both sides, it will just continue to get worse.
