Should I take a test

Adalys

It’s been 9 days now since my missed period, I have taken a test a few times and it says I am not pregnant but I have been throwing up lately not eating like I used to so I don’t know if I should wait a little longer. I am so confused I have been overwhelmed with anxiety to know if I am or I am not, my period is never late. I went to the hospital and they tested me said I am not pregnant, but I don’t know what to do. Is it to early to be taking a test?
