32 and TTC for the first time!

Hi everyone! My name is Brittany and my husband and I are trying for our first baby. I’m in the middle of my two week waiting period. I have not had any implantation bleeding but that doesn’t always occur right? I have some mild cramping but nothing else. This app says I should take my first test tomorrow which would be 6 days before my period would start. Is that too early? I know it’s a long shot conceiving on our first try but just looking for others who may have some experience and who may have any advice!
