I'm kind of freaking out because it was so sudden and I don't want the embryo's to die, any suggestions please?!
In all sincerity, Better to have the embryos die, than to have the neonate chameleons suffer, then die. If you cannot commit 100% to the care, knowledge, and (pretty difficult for you now...) the experience needed to maintain the lives of the babies, it's best that there are none.
Also, personal observation/experience; If she is not laying the eggs and instead "pooping" them out, then there is a higher risk for a prolapse and complications of her health.
FOR LAYING FEMALES:
I use Sand, Topsoil & Coco fiber mixed together. It should me misted with water, then mixed up, and misted again, and again, under the mix has a strong feel to it so that if she digs a long tunnel it will hold up and not collapse. If shes in there for extended amounts of time you'll need to mist to keep the soil moist enough.
I do mist for drinking water in the morning, no dripper as you don't want to saturate the bottom of the tubs soil. I usually place a few silkworms inside in the event that she will eat- although many will not. I usually put my computers webcam inside to spy on her. If she sees you she could abandon the whole shes digging and eventually become eggbound and die.
The laying bucket, minus the cloth that usually covers the hole not occupied by the light. The hole in the lid that is not covered by the lamp I cover with a type of perforated fabric that allows airflow.
I don't use a heat lamp, I use a florescent Coil, or a low wattage incandescent. You'll need to monitor the temperature and test a couple bulbs probably.
Provide vines, branches, and a plant as if it were her real cage.
