BLEEDING GUMS.....is this normal?

Veronica
This is my cutie pie Teddy who is gonna be 9 months on the 9th of  March. I know he's cutting his two top teeth but last night he woke up crying and had put blood on my shirt! I noticed when he bit on a cold washcloth it also had blood. 
Is this normal? My worry is he is biting his bottom teeth into his top gums and making it bleed. Anyone else going through this? 
I've added a pic just because I love showing him off ❤️
