Im sorry I think your eggs are no good. Here is a link with some nice big clear photos of what eggs should look like and info on how to care for them.

I hope I am wrong... but... pretty sure im not. Did you have a tray full of sand for her to lay them in? If you bought her from that pet store gravid and they told you her expected date then you should go back in there and demand compensation through maybe discounted or free food or something. I would be really dirty with them if that were the case.
If you mated her yourself but didnt know gestation periods and merely asked the pet store instead of doing your own research then you only have yourself to blame
Don't mean to sound mean lol Next time you will know though right
But being unsure, if I were you I would go about asthough they were good eggs at least until an experienced breeder replies with a more definitive answer. Looking at pics of healthy eggs though yours dont look good. If its her first lot too, she may have just had a dud batch? Happens with birds alot, sometimes their first clutch just isnt right, but a second clutch will be fine.
BTW... Im pretty sure beardies are capable of laying a few clutches per season... so put a sandy tray in there for her to lay them into and keep your eye on her. Check out the website I sent and do some google searches write it all down/print it our and keep it next to your girls enclosure and check on her when ever you get the chance. If you dont have an incubator, look up making your own
Im sure it wouldnt be too hard with a thermostat, patience and the right heating.
BTW I have zero experience... just trying to put out some suggestions from an inexperienced point of view... that is what I would do in your situation. Going out and buying a $400+ incubator doesn't appeal to me, I would be making one xD I have made doggy incubators/humidycribs before ^_^ My own whelping boxes, holding pens and now Im making my own reptile enclosures.
Best of luck! I would love to hear what happens and lets hope next clutch goes way better
