Crying over stretch marks :(

38 weeks and 3 days pregnant and woke up to my first stretch marks. I know it's a stupid thing to be upset about but I'm feeling pretty gutted over it. I'm so grateful to be pregnant and I can't wait to hold my baby in my arms. I know when I meet him, I won't even think twice about my stretch marks. But he's not here. I have no signs of labor coming anytime soon and I'm just feeling so down. Any other mamas can relate? :(
