Should i get another Guinea Pig?

[GuineaPigxxx]

At the moment i have a 3x4 C&C cage with 2 female teddy pigs that are both 3 months old. I am planning to build a 1x3 loft with a ramp leading to the main base of the cage. therefore, i was wondering if i could get possibly 1 or even 2 more guinea pigs to add to my herd. i thought that 2 pigs would be better as if they do not get on very well, i can separate the cage and have two 2x3 cages.
So at the moment i am really stuck, can someone plz help me?@)@)

I would not have three piggies as often one is left out and the others gang up on them. Two sounds perfect as they are getting on with each other.
