I got my tongue pierced 3 days ago. To day I woke up and there was bried blood in front of the piercing on the bottom of my tongue.when I got back from school white stuff was there. Is it infected? The top side of my tongue looks normal. Exceped for the swelling and the irritation I get from moving the piercing up and down my tongue

Yes, that is a sign that there is an infection, you should get it checked.
