Really confused???!!???

My period was supposed to start the 23rd but still hasn’t made its appearance. They usually are regular so for me to miss a period is super unusual.

I decided to take a test on Monday (this the test 👇) & it I swear it showed a faint line... (I did not use fmu I took this test around 3pm)

But then I decided to test again this morning w a different brand & came out negative 👇

I don’t get how a vvvvfl could appear on one test but then another nothing shows up. Could I be testing too early?
