Seeing the baby move

So I'm 20wks and 5 days today, according to my due date of June 15th. I've been measuring about two weeks ahead the whole pregnancy though. I've been able to feel my baby kick since about 14-15 weeks. It used to feel like butterflies or popcorn, and now I can feel him stronger. I can feel when he moves around, not just a pop here or there. He was squirming around this morning, so I laid down and pulled my shirt up. I saw my belly moving!!!!!! It was amazing to see! Kind of weird at the same time honestly, but so cool!! Has anyone else been able to see the baby move on the outside yet? Prior to today I have noticed on two occasions that my stomach was more bumped up on one side, but then it would just kind of flatten out. Today I actually saw little flutters come through!
