I got heaps of them when I had a growth spurt at 13 all up my thighs and bum, so I wasn't surprised by getting them while I was PG.
They have faded heaps but are still noticeable. My dad made a comment once when I picked up Angus a few weeks ago and saw them when my top rode up a bit.

What can you do? Wear them as a badge of honour I say \/

I did massage palmers coca butter while I was PG so that may have prevented them getting worse.
