This is my first pregnancy too, currently 25 weeks. Been using alternate palmer’s stretch mark lotion & bio oil (: can get from venus or shopee. Start using stretch mark lotion/oil early for prevention! I started during mid first trim
I used mama’s choice since week 5. Best to start early :) However do note that stretch marks are also genetic, if your mom have bad stretch marks, you’ll more or less have abit nearing birth. Just don’t scratch it!
