Just a little peace of mind...

I know its normal for movements to be sporadic and kick counting starts around 28 weeks and i have been feeling him move a little through out the day more in the morning when i first wake up. Its just last week he was going crazy in there and the movements were harder than they have been this week. I did have a pretty busy weekend, but i have been eating and sleeping more this week and gained 4 lbs in about a week. Could this be a growth spurt? I am currently 23 weeks
