ttc but ovulation test never shows positive

Mallory • dogs and food!!
Has anyone experienced ovulation tests never showing a positive? I've been testing for 2 cycles now and I do get my period monthly but I've never shown a positive LH surge. Is it possible I'm not ovulating even though my periods are fairly regular? Also I'm using two different brands of tests so I know it's not the brand or a bad box. Any help and feedback is appreciated :) thanks!!
