Confused

I was suppose to start my period the 24th. The app said I ovulated on the 8th. (Which I don’t think I did) I think I ovulated a week later. I got a blood hCG test done on the 17th and it was negative. Could have it been too early still? Should I take a home test since I am four days late? Has anyone gotten a negative beta test and ended up pregnant because they took the test to early?
