My biggest insecurity....

I’m a young mom, I’m pregnant with my first baby and all the people I know my age are enjoying college and all in the best shape of their lives. I don’t mind that im going to be a young mom and that my life took a different turn thats not what gets me sad. Because I am excited and I know everything happens for a reason but I feel so insecure about my body. Ive already gained 12 pounds. And I have stretch marks all over my body. They cover my entire body I get sad I feel like ill stay big and like my stretch marks will remain super dark. Have any of you ladies gone thru feeling like this? Can I see you’re guys weight loss progress ? And see your before and after for motivation and reassurance that if you girls did it I can too? 😭
