when to test??????😩

my last period was jan 2nd or 3rd. i believe i ovulated jan 13th/jan 14th bc of the ewcm (i only get it when i ovulate). anyways this tww is killing me😩 how many dpo did y’all start testing and got your bfp? i had a chemical pregnancy last month in dec so i’m hoping for a sticky bean this time around.
