Help!!!!!! urgent!!!! dont know what to do!!!!!?

our cat is pregnant we took her to the vet to see if she really was pregnant (this was last week on wendsday) the vet said she was due in about 2 weeks. she was moving around acting normal thismorning and then about 2 hours ago she went under the bed and shes just been laying there on her side ever since. does this mean shes about to have her kittens or is she just being lazy? she hasnt done this before. she was a stray that had wild kittens last year exept they all got eaten by coyotes and ever since then she has been hanging around our place and we saw that she looked pregnant so we got her checked to see if she was and if shee was we woud have to get her to my friends place that knows how to take care of the kittens except she was supposed to pick her up yesterday but she couldnt and now the cat is here still lying under the bed on her side. you can still pet her and stuff and she will purr but i dont know whats going on. sorry for the big ong run on sentence but im worried she might have her littens here and now. and she hasnt had any shots because the vet said sshe could have them until the kittens were done nursing.
