Tik tok song

OK so a few months ago I saw this video of a girl on tik tok going through her pregnancy timeline and shit and it had this really cute song in it. I forget how it goes so I can’t look it up but it’s something along the lines of “waiting for you” or something like that. I’ve seen it a few times on the video contests but now that I want to find the song of course I cant figure out how the lyrics go to look it up. Does anyone know what song I’m talking about ?
