Anyone struggling with stretch marks?

I've always been so cautious of my body since I started gaining weight and not once did I have stretch marks on my stomach before my pregnancy.

When I was just 2 1/2 months along I started noticing them and now it keeps getting worse. I know it makes me sound like a bad mother to say that when I know having a baby would mean not having your body the same as it was before pregnancy but it just makes me feel bad and worse then I did before because not only am I thinking of the excessive weight gain but now also stretch marks?

I love my baby and he's the biggest blessing I could of ever asked but sometimes it's just the insecurities that get the best of me sometimes.

Any positive feedback? Someone going through the same thing?
