Part 2 of my cat being in labour?

Sorry I don't know hwo to comment on your answers. Thankyou very much you are all very helpful. I don't think she has been in active labour since last night, but she had mucus etc yesterday and was hiding out all day and last night, and looked very uncomfortable and restless. I checkec on her every couple of hours through the night and she never seemed to be in any distress. I noticed at 11am this morning she has one baby, and I can can feel more movng around in there. I don't know how many she has for sure but I am sure I could feel 4-5 the other day. It has now been just over 1 and 1/2 hours since the first kitten was born. My other cat had kittens last week, but I didn't see that birth and she had 4 through the night, including 1 stillborn. I think I am freaking out more with this one because I feel bad for not being there for Clunk on Thursday. She is definitely not in any distress and she doesn't seem to be pushing. How long is the max time to wait before seeking help?
