Question

Christine • Momma to 1 Beautiful baby girl👧🏻. 1 Miscarriage 👼🏻. Working on my Rainbow baby 🌈👶🏻
Is it possible to have a complete negative one day and then a positive the next ? My last test from 2 days ago was pretty negative I think , I thought I saw a vvvvvvvvf line but my sister said looked negative. And here I am 2 days later, a day late on my AF and I'm nervous to take another test to see it negative😞
