Is there still hope?

So im now 7 fays late on my period. My period was supposed to start February 9th and nothing. On February 4th snd 5th i had brown kida medium spotting then went away. Yester mornong my boobs and nipples start to become very tender. I took a cheap dollar tree test came bacl very negative, so would it jjst be safe to say this month not my month and im not pregnant?
