2nd Pregnancy!

Okay, So with my son i gained a total of 61 pounds & Got A LOT of stretch marks! On my Stomach, Legs, Even the back of my knees!! 
& Im SO scared that now they'll get Way Worse & I'll gain a lot of weight as I still have 10lbs of baby weight left.. (my son is 9 months old)
Anything that actually works for Strech marks?
