Confused

Co

I took some tests about a week ago because I was nauseous (I knew it was too early, but didn’t know why I was so sick) they were very faint . Fast forward a week and now I’m 3 days late and I’m never late still very nauseous and have no appetite, but now my tests are negative 🙄😩 the first two are my tests from tonight . Last test is from last week .

This is my test from last week .
