She lost her plug on Friday night its now 2,26 am on Sunday morning nothing is happening all she is doing is sleeping eating and wanting strokes however late last night early this morning she has done a massive pooh its quite runny. And as she's sitting next to me every few minutes there's a smell like rotten eggs should I be worried I have no idea about cats pregnancy and labour I have read you can feel the kittens moving but she won't let me near her belly only her head please help should I be worried

The plug was a like a green runny boogie

It's time to go to the vet. Without seeing your cat, there's very little we can do. It's best to see a vet about this.

After that period, it's possible that the kittens are dead. Cats do not always go into labor if the kittens are stillborn. The green color leads me to believe that might possibly be the case, since green usually means infection.

I would suggest taking her to a vet. If the kittens are dead, and/or there is an infection, it could kill her.
