Do all breasts increase during pregnancy?

oh god, this is really weird and silly for me to ask you adjectives... but here it goes...
I am presently in my 15th week of pregnancy and my boobs go from an A to a B so far... well I be just wondering, since I hold been other kinda insecure about my small breast, do they really all grow 2 or more cup sizes and do I own a good destiny to have a fuller chest after breastfeeding?! They come across only sore within my opinion but my friends reflect they actually already look bigger, can I expect them to grow more soon?
Ha ha, appreciation to all of you, I know this is unexpected and all, but I'll be blissful to hear you about this, thankfulness.

How do I lose weight? Get rid of my stretch grades?

Yup they grow as much as needed! Once your milk comes in, their size may fluctuate as your body adjust how much milk it needs base on the baby's demands.
Congrats and best of luck!

PS Enjoy the boobs very soon bc once the baby is born they are no longer yours!! :)
