Hi! I can assure you that it won't survive, so young and with that rot it won't last another two days.. you might as well start over, remember that it's better to start with moist soil and not water for a few days while the plant grows, and when you see that the soil is dry, you can mist it with water, until the beginning of the second week of vegetative :) this way you avoid too much moisture from rotting the stem! When I germinate directly in the pot, I moisten the soil well, cover it with plastic wrap, and wait for it to break through the soil before removing the wrap. After that, I usually water again after another 3-4 days :)
