18 weeks and belly visibly twitching

Andrea • FET 4/12/16 ❄ Our snow baby was born 12/26/16 👶🏽
I feel the baby inside moving right where the twitch is. At least I think I do. Am I crazy or is the twitch I see on my bellythe baby moving? It was slow at first and then it started going faster and I got so scared I started crying. I know he's okay it was just weird and I had no answer so I got scared.
