Baby kicks non stop

I am currently 21wks and last night I had the most amazing but uncomfortable feeling ever, I would usually sleep with a pillow under my belly for comfort and support but for some reason last night it wasn't working.

So I decided to turn a but and sleep halfway on my stomach, while in sleep I could feel something strange like the side am laying on my skin was moving I thought I was dreaming so I wake up but still on my stomach slightly because I could no longer continue sleep.

But it wasn't a dream at all the baby was actually kicking on the side on my stomach I was slightly laying on that I could no longer sleep and how I knew it was kicks is because before turning I placed my hands on my stomach and actually felt the kicks so I had no choice but to change my sleeping position so baby would be comfortable that's just amazing and with kicks that actually wake me up.

Has this every happen to any of you moms to be.
