She lost her mucus plug on Thursday and her temperatur dropped on Friday. Yesturday she started straing and then stopped at about 6 30 and nothing has happened since. Today I found some greenish mucus coming from her vagina and am very worried.

I'm sorry no one got to your question, sooner. Hopefully, I'm not too little, too late.

If you haven't already taken her to the vet, and she hasn't given birth, then you should. It could be the kittens are too big for her to birth, or one or more are stillborn. Stillborn kittens are harder for a queen to birth. The greenish mucus is worrisome, and could mean some sort of infection.

I hope she's OK.
