Cameo gives me a few gray hairs!

I am whelping Tess' litter today and have been awake for 24 hours. I am worried about Tess and her last puppy because it is taking forever to have her and Tess is exhausted ! I take a break from worrying about Tess to check on Cameo who is 3 feet away in her whelping box with her thriving pups. Cameo stands up and begins to sway from side to side. I check her gums they are very pale, not good. I call my vet who advised us to take her to the emergency vet at 4pm on a Friday afternoon...traffic will not make it easy to get there. I break out in a sweat and call a good friend to meet me there since I am exhausted and can not make good decisions in my present state. I get her in the car and she seems ok, no longer swaying and back to her happy self. At the vet we get out of the car with a box full of puppies and Cameo. The vet asks how long her face has been swollen....oh God it wasn't like that when I left the house. She is having an allergic reaction to something most likely an insect bite, I'm thinking ground wasp hiding in the leaves. She was never out of my site in the yard so I know it can't be much else. The vet is very sweet and doesn't make me feel stupid, they give her a small dose of benadryl, fluids, and do a small amount of blood work. Everything checks out ok, my pulse goes back to normal. Now I go home to see how Paul is holding down the fort....all seems ok , everyone is alive though there was an incident with a Sharpie and the newly painted wall in my office but the 2yr old Picasso isn't talking !
