are my beardies eggs fertile???

so my female beardie laid eggs yesterday and i had no idea she was even pregnant. she laid 12 but all of then are dented. ive read that that means they are infertile but when i checked them this morning the eggs had veins and i even saw the little dragon and its eye. she still has more in her stomach that i can feel. im worried she wont lay them so how long does is usually take for the next clutch? this wasnt planned at all. i have the eggs in an incubator at 83 degrees in a tub with media in it. im just worried the eggs are duds. please help.
