Is my cat in labour?

[Miss-Ladybug]

We thought my cat was due in roughly 2 weeks but she has been acting VERY strange today, whining and falling over on her stomach.
A few hours ago we found her tightly snuggled in a corner of the spare room, like she is making a nest.
She has been investigating places to nest for the past while but this time she is actually just staying there. She hasnt even used her chance to have a nose round the spare room (we normally dont let her in there).

Is this like a phantom labour or is it real?
Thanks.

possibly,they tend to go for the weirdest places to give birth tend to hide away!!!
