Hi Lesh,
I've been experiancing the exact same thing, Ob did a scan last week to see what position bubs was in and it turns out that he's sitting breech, curled up in a ball with he's legs up hear he's face - i'm guessing that's why i wasn't feeling many kicks, he must of stretched back out again though as i've started feeling him kick again the last one or two days.

Like you said bubs probably hasn't got as much room in there now as he/she did have which is why they can't kick you! All the best, i hope the last 9 weeks don't drag too much for you
