stretch marks/moving/mom stressing me out

I think I'm getting my first stretch mark! 😢 Has anyone else started getting them? I'm 23 weeks Sunday. What have you all used that you swear by? I just ordered the mustela cream. I've been using oil but it got sent with my husband before I moved and he can't find it now. I'm also in a transition as I just moved to Maryland this week. I'm a stressed out momma that lets her mom keep stressing me out too!
She FaceTime me this week and said my face was puffy and looked like hers while pregnant with me and she was on bedrest with me. I know it's my allergies and sleeping on my face because as soon as I take my allergy meds that are safe with baby it goes away! I don't know what to do. Now I'm scared I have gestational diabetes.
