Vaginal discomfort

Ok this may be really weird but I have been having a little vaginal pain today. Had sex about 4 days ago... it just feels like it’s kinda being stretched at this very moment if that makes any sense. Not sure why it would be feeling like this now... anyone else have these issues? Or ever had this and know what could be causing it? I just don’t feel like it was the sex I had 4 days ago
