Hoping someone can help me out here,

Has anyone gotten negatives until a few days after their expected but missed period? Then gotten a BFP or VVFL?

I’m due for my period tomorrow but have had completely different symptoms then any other period, I’m not on birth control (pull out method)

<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I’m due tomorrow, my other app says I’m 3 days late, I got a negative this morning even tho I believed something was there /:
