HELP!!!

My queen is a 22 months old SFL, her weight is 2. 640kg. She mated 17-20.01.17 and counting from the 20th she's already on her 66th day but no labor signs yet [emoji]128577[/emoji] 3 days ago she had discharge i thought her waters broke but nothing until now. The vert said shes healthy and the kittens are normal (3 weeks ago), he also said that the ultrasound shows 4 kittens BUT her belly is so small u cant even tell she's pregnant, IS THAT NORMAL? her nipples are pink and erect but they are also very dry, like there are dandruff sort of things around the nipples. I havent checked for milk coz im dont wanna hurt her, but IS THAT OK TOO?
This is my 1st cat and 1st litter please help coz I really dont wanna have dead kittens in her belly but the doc says I should wait till 69th day. WHAT SHOULD I DO?

Some cats do not deliver until 70 days. The dandruff flakes are dried milk. You can apply olive or coconut oil to her nipples to keep them from chapping.

She should go into labor naturally in the next few days. Did you have an x-ray done to know how many kittens?

Everything sounds normal to me. Try to be patient! [emoji]128522[/emoji]

What does SFL mean?

Did you breed her on purpose?

SFL = Scottish Fold Longhair if I am not mistaken

My guess is first time/beginner breeder from the age of the queen and specific breed. So purposeful breeding.

To OP, I know it is scary and stressful but give nature time before you panic. The vet said to wait so all you can do is wait. Hoping everything goes smoothly.
