Stretch marks after birth

Hey mommies🍼 FTM here and recently had my beautiful son who I love more than life. I managed my whole 10 months of pregnancy without one stretch mark and then today when I went to put lotion on my belly I saw two tiny stretch marks. I couldn't believe it. I was shocked and a little sad. I'm three weeks postpartum and was wondering if this happened to anyone else? And did they go away? They are light not dark and there isn't s thing wrong with stretch marks don't get me wrong but I'm shocked and was almost prideful about not having one, guess that's what I get lol.
