Phantom Baby Kicks? But not pregnant??

So Hi. I took a test 4 days ago & today. Both negative. But I feel like the one I took today had a faint line but anyways I have been feeling something in my stomach moving. Its not organs or anything like that. Idk what it is! Like my stomach feels super tight & its bloated. Idk what to think! I know you guys aren't doctors but what are your opinions??
