3 yr old pregnant Guinea Pig - First Litter

Question
I just realized my pig was pregnant and going to deliver any day now.. Of course I'm tremendously worried about this as she is about 3 yrs old with first litter, I feel terrible.. From reading up and things about them, I have checked her dilation frequently in the past 4 days, and she seems to be about half the width of my finger dilated, except the bottom is very open but the towards the Top goes more shut and feels like there's something in between that closeness,  is that a pregnancy plug or something, I didn't want to poke and prod too much, but I'm just so scared for her.  She's eating and drinkig Just Greatly, as always!  She's acting a little nervous though and keeps eating timothy hay like its going out of style. Like she's preparing for it or something.. I wondered what you thought about her even being dilated at all at this age.. Do you think she may have a chance?   Thanks So Much in advance... Heidi

Answer
Did you breed her?

I would leave her alone. Handling her will stress her out. Have a good vet lined up in case of complications due to her age. Has she had a litter before? If she hasn't it is more risky.
