How did the hair tie/rubber band trick work to extend using regular jeans in your 1st trimester? Didn't work at all for me!

I had been told by many women that they either never needed maternity pants or that using a hair tie/rubber band through the buttonhole & around the button kept them in their regular jeans until well into their 2nd trimester. This NEVER worked for me any time I tried it however: the pants either had to still fit on their own or get temporary retirement bc this 'easy fix' caused me definite discomfort in my hips & just still felt tight even though it made my jeans look loose! I think my body just is already carrying LOW! What y'all think of this??? Please comment 😊. Currently in maternity jeans & sweatpants or leggings or similar lower body attire. I even had to start only wearing spandex or loose panties by 5/6 weeks!
