Should I be worried?

Melissa β€’ My husband and I were blessed on November 19 2015 with our son Nolan! Currently pregnant with baby #2 πŸ‘¨β€πŸ‘©β€πŸ‘§β€πŸ‘¦
Since the begging of this week I've been feeling my son move pretty frequently throughout the day and today I haven't felt anything usually I'll feel movement all throughout the day and a few hard kicks at night.. Has this happened to anyone should I be worried? I'm 22w4dΒ
