63 Days pregnant, No signs? Mucus dis charge?

Hello y'all. I am Desiree, and I own a beautiful dog, Koda.

Just in case I get a lot of "Why would you do that
to your dog" or "There is so many dogs in shelters"

I'd like to tell y'all this was an accident. I took her for
a walk like I do everyday, thinking her heat was over.
My dog only likes one dog in our 'hood, he is a pure
bred husky and they where playing, the owner noticed
my dog was putting her tail to the side so he grabbed
the leash from me, and before I could snach up her leash
he was also grabbing me (Bottom, and thighs, ect.)
More to the story but I wont bore y'all...

She is now 63 days from that, She has her own quite
place in my closet so I can hear when she is giving
birth so I can help her if she needs it!

I have done all my research, talked to the vet, all the if's
and but's; but I want y'all opinions!

She did some digging in the closet to get comfy, but other
then that she is being normal? No it is not a false pregnancy, I can feel puppies moving around in her belly!

She has been sleeping a lot today, and drinking like she is dehydrated! I let her out to go pee and a LONG white string of what looked like snot came out of her "You know what" and she is being very clingy! She is eating here and there.

I know what signs of first stage is, but have y'all had different ?

The discharge is something i'd like to know about, is it her plug? May she go into labor tonight or tomorrow is so?

Thanks y'all!

What breed is she?

Smaller and mid size breeds there maybe reason for concern, large or giant size breeds, I would not worry as much.

Koda is a German Shepherd X Rottie.
