Missed period/Negative test

Hi everyone. So I am a mom of 2 and I’ve taken at home tests with both. I only required one test to show positive. I am currently 5days late and my husband and I were intimate all throughout my ovulation period. Last weekend I was super nauseous and I’ve been so tired this whole week, I’ve also been eating more than the usual. I’ve taken FOUR tests (I know I’m crazy) and they all say negative. I’ve never missed a period and I’m always regular. So these negatives are blowing me because all the signs are there right? I do have a Drs appointment next week Wednesday with my OBGYN to get a clear answer.

But what do you all think? Is it too early to test?
