Is this a mucocele? PICS INCLUDED

Hi Guys,

I think I posted in the wrong part of the forum, so i'll create another here. 

I've had a lump on the inside left of my mouth for around 3 weeks now, and I'm wondering if it is a mucocele. It doesn't hurt and It seems to have stayed the same size. I'm seeing doc next week but if you guys could clarify it would mean alot.

Cheers.

P.s sorry for the poor pic quality. :)
