How do you count kicks?

Samantha • First time mommy due with baby #1 September 2017

Hi ladies. Doctor said I should start counting kicks, but I'm 32 weeks and feeling like the baby is a little too big to be "kicking" like he used to. Now I feel more rolls/twitches/hiccups and I wonder if it's because there's not enough space? Do the other movements count as "kicks"? Thanks!!
