When I was pg with dd1, I was stretch-mark free until 37 weeks when they suddenly all popped up out of nowhere 
They have faded significantly over the past 18 months and are now very pale scars, but I'm now 22 weeks pg again, starting to get a bump and wondering what will happen to my poor belly?
Will my existing stretch marks darken again? Will I get new ones? Am I completely wasting my time with the whole bio oil malarkey?
