Trying not to get too excited

When I was clipping Buttercup's toenails last night and holding her, I think I felt a kick! I had almost lost hope she was pregnant, but she could have a baby as late as the end of February, so there is still a slight possibility. Anyway, the kick was very faint, but I distinctly felt it twice in the same spot. So she either had bad gas or she has a little piggie on the way! I am trying not to get too excited...but it would be so fun to have little piggie babies! Why don't they make pregnancy tests for guinea pigs?! I wish I could know for sure one way or the other. Guinea pigs are the cutest baby animals ever!
