We are 45 days now from last mating. when would you normally say you might see or feel puppy movement?

We usually saw puppies moving around by week 7.   Sometimes mine would 'hide' them up under the ribcage making it more difficult to determine movement.   And with a big litter, being more 'cramped' in there meant less movement too.

So another week or so. Interesting what you say about a big litter too.

With mine I have RARELY EVER SEEN puppy movement, ditto third stage contractions. as they are broad and deep bodied short loined and thick coated.

Its easy with my breed to see movement at the right stage..its so transfixing & can spend ages just watching...
