Fetal movements/patterns

Hi! Am 30 weeks plus today. Have been told by gynaes that I shld alrdy know my baby pattern so that I can look out for reduced movement but I CANT TELL baby pattern and it's freaking me out everyday. There can be days where baby moves every minute. Like I can have 30 kick count in an hour, for hours. And then on other days, just maybe 1 - 2 kicks in 5 hours, and I won't be able to meet my 10 kick counts in an hour. It's so confusing because I'm confused with quiet days and reduced movements and it's really scaring me. Anyone else gave the same issue? What do you all suggest? Cold drinks and sweet stuff don't really work for me too.
