Bearded dragon eggs ?

Alright so im very confused. over the summer i bought a bearded dragon from a friend. they did not know the gender of the dragon but when i bought it i was 99% sure it was a male because when i checked it, it had two large lumps at the base of its tail right by the anus. they said the beardie was almost 5 years old and they have had it since it was a baby and it had never once laid eggs that they knew of. figuring this i just assumed it was male. It never showed ANY signs of aggression around other bearded dragons or any animals at all, never bobbed, never waved.. NOTHING.. the only thing it did do was attack its reflection in the mirror but all it really did was run into the mirror and trying and climb up it. everything was fine up until this afternoon when i got home from school. Now whenever my bearded dragon poops its just .. well.. poop, but it has the white sac like thing along with it. i read this was normal so i thought nothing of it. they were usually shaped like a long oval and were mushy. well, this morning i woke up and there was one of those white sacs in his tank but it wasn't as long it was more of an egg/oval shape and it was not mushy or anything, it was fairly hard and it looked really wrinkled. to give you more of a visual, it looked kind of like a large grub would. it basically did not look like the normal white sacs he usually makes when he poops. and there was also no brown poop coming with it, it was JUST the white poop. i was a bit concerned but i didn't think to much of it due to the fact i was running late for school and I just assumed it was poop and i left for the day. when i came home to my surprise there was about 7 more of those white sacs and they looked like the one i had found that morning except for one of them which looked very different. it was larger the all the others and it looked like a small egg and it wasn't wrinkly or anything. it was bleach white and smooth. i picked it up and it felt like a ball of leather with liquid in the center. me being curious popped it open to find a yellow liquid inside of it. the whole time i was doing this my beardie was eyeing me down to. I was really confused because i thought they could have been eggs but i thought my beardie was a male. i was thinking about buying a female for him in a few months but then this happened so im not sure anymore. im just very confused and i want to know if there is anyone who can help me. i would be heartbroken if there was something wrong with my beardie and it was to late to do anything, i just need some help, please.
