Is my baby bearded dragon impacted?

My bearded dragon pooped the day after we got her, and then she hasnt pooped for the last 2 days and ive fed her 2 crickets those days.I give her lettuce when shell eat it. The crickets are about the distance between her eyes, maybe a little bigger. (I HOPE THEIR NOT CAUSING THE BACK UP)...I used repti sand,(the same the pet store had her in when we got her, but she pooped so their sand didnt do it, right?)....which im REALLY SCARED NOW! i read about impaction and how it makes baby bearded dragons not go to the bathroom, because it eats the sand. Well, i read this article on Beardeddragon.org and this guy Blacklightsouth sand if you poor water into the repti sand, mix it throughly and let dry it will become hard packed like the stuff in austraila is, which the dragon cant eat! I just finished doing that (also had to flatten the wet sand, VERY HARD!) and put on my beardies basking lamps on it. waiting for it to harden or find out that this guys full of it. My beardie is female, about 5-6 and a half inches long. I LOVE HER SO MUCH, I DONT WANT HER TO DIE. (her names Izzy) PLEASE HELP ME, im so scared right now im about to cry TT_TT !
