Taste bud, swollen andwith blood?

After I ate an ice pop I felt a bump in the tip of my tongue and when I looked in the mirror it was a dark red and when I moved it around I noticed the bottom was a regular pink like the rest of my taste buds. I ended up squeezing it to make sure it was blood, which it was but this has never happened to me. It didn't hurt. I don't remember bitting myself or burning myself. So what could have been the cause of this? Is it a sign of something?

Thanks.
