Stretch marks 🙄

So I’m 15 weeks and my sister in law asked if I had started showing at all. I was wearing a baggy hoodie so I lifted it up to show my stomach (I’m barely showing, just still chubby). I’ve got very very very red stretch marks and she goes “OH MY GOD WHAT ARE THOSE?! You’ve got stretch marks already?!” Thanks, that totally helps with the fact that I’m already self conscious 🙄 You ladies have any tips on how to get the stretch marks to calm down a bit during pregnancy?
