Does this sound like implantation?

Last night when I was trying to sleep I had pinch like pains (off & on) in my side & also a little bit the night before that. This morning (7am) when I went to the bathroom I wiped & the tissue was light pink. I went to the bathroom not too long ago (11:30am) it's gone. It's not there anymore. 
I should prob also add that it feels like little flutters (idk how to describe it) in my tummy & I keep throwing up a little bit in my mouth. I was doing that since I woke up. It's still doing it lol. 
What do y'all think?
