Are you certain that you have one female, and one male?
It seems like you planned for these two to eventually be housed together, if I'm understanding this statement correctly.
"I have kept wrangler in a seperate cage since the day I have gotten him, I have let the two roam around on the floor together supervised but they have not been in the same cage, I wanted them to get used to each other, I didn't want to just toss another in with JuJu and hope for the best."
...that seems like you wanted the two pigs, knowing that their opposite sexes, to meet each other supervised during floor time before putting them in the cage with one another.
I ask that you please, from now on, permanently keep the two separated. Even supervised, it is not advisable to let males and females interact. It just takes 3 seconds for the "deed to be done". You can turn your head to look at the window, and wahla, it's too late.
If she is pregnant, hopefully she'll have healthy babies. Pregnancy is very hard on guinea pigs though, and even if her babies aren't lethals, it isn't uncommon for a pup to be still born. It is also a possibility that mom can die from complications of pregnancy. I'm not saying this to scare you, but it's important for you to be educated on the matter so you can fully expect and prepare for all possibilities. If she has at least a girl and a boy, your problem is solved. Keep a girl to pair with mom, and a boy to pair with dad.
If she does not have any boys to pair with dad (or any girls to pair with herself), you'll have to get him neutered so he can be safely kept with the females. Or adopt another guinea pig of the same sex, to be paired with either mom or dad if their are no babies of the needed gender. It's not really fair to keep guinea pigs single, they really do need a friend, but they need a friend of the same sex to prevent unwanted pregnancies ^.^
And if she's not pregnant... I strongly suggest either getting the male neutered so they can be kept together, or adopting another female and male so each of your pigs has a friend.
