How is she acting? pretty normal, or frantic? if she meows, starts pushing and no babies after an hour of pushing, call your vet. Usually, a calmer, normal-acting cat is fine. Please keep in touch!
I can feel the kittens but no movements it is really worrying me is that normal also no contractions can be felt she is a lot less active at the moment sleeping a lot more and not playing much.
I think you are worrying too much. She may still have a couple of weeks left. You said you thought she was about 6 weeks along on April 26th when you started your thread.
