Is it normal that one breast is bigger?

Oh okay! Thanks! Ur guys' answers helped , a lot! :) I'm no long worried! :)

It's common to have slightly a-symmetrical boobs, although typically this is barely noticeable and only apparent when feeling or measuring for a bra. If it's a large difference and one is very obviously larger/smaller (to other people, not only yourself) then that is less usual :)

It's perfectly normal! My left breast is slightly larger than my right.

yeah but you also have one breast that is smaller than the other so they cancel each other out.

So thats why i like the left breast better.

Totally normal though i have perfectly plump boobs, it's just like some guys, one sack can be bigger than the other :P

i guessing yeah it normal because my left leg is bigger than the right leg.

I think my left one is slightly bigger as well but it isn't noticeable. My ex had one breast that was quite a lot larger than the other but I didn't mind. She was still pretty to me.

I don't know the reason, but the left breast is usually bigger. So if they were both the same size I guess you would be abnormal.

How much bigger?

Yes it is perfectly normal for your left to be bigger. Your heart sits in the middle of your chest but it's more muscly on the left side. This muscle takes up more room (hence why your left lung is smaller) and also pushes outwards a bit so this is why your breast is bigger on your left side.
Hope that helped!

If you are breast feeding, let your baby hit the smaller breast harder than the bigger one.
