Is it normal that my left breast is bigger than right?

Terrible thing, my left penis is slightly larger than my right one.

My middle breast is the biggest.

So normal you'd probably be hard-pressed finding a woman who does NOT have naturally slightly asymmetrical breasts.

Yep! My right breast is bigger than my left but not by very much. Other people will probably notice it even less than you do, so don't worry about it :)

normal cos it is where your heart is. google it

perfectly normal

Its normal...my left breast is also bigger than the right one

Totally normal. I don't know of a woman (who hasn't had surgery) with perfectly symmetrical breasts.

yes its actually very common.
Natural boobs are almost always slightly asymmetrical.

My right breast is slightly bigger than my left, and I'm a dude. I think It's pretty normal.
