Hey guys I have had my tongue Pierced for 3 months.
Your tongue turning white is normal. What are you using for mouthwash? If its listerine You should be diluting it 50/50 with water.
The discharge that is coming out is normal as well along with some bleeding.
I woke up the second day of having mine with a ring of blood around it.
Also if your tongue tears it will heal in time and if this takes place continue your aftercare until it does.
You can change your barbell as soon as 2 weeks after the piercing(i had to change mine then because i kept biting the ball and my tongue tore but I would advise waiting at least 3-4 weeks.
