2 negative tests

So my hubby and I have been trying for baby #2, I took two tests when I had my period missed by two days. They were unfortunately both negative. But it’s day 6, and no period in sight. Is there any way those two tests could be wrong??? My boobs have been sore and what not.... but either way I know those are symptoms for a coming period, but no period in sight 😥. I don’t want to be too hopeful but we did it all my fertile window and also on my ovulation day......so it’s difficult to not be hopeful
