Terrified I'm having another MC or Chemical 😔

AF is officially two days late and I took a test this afternoon and got BFN or possible VVFL. One of the girls on here was kind enough to tweak it but I'm feeling a bit down. Shouldn't I have a BFP by now and not faint lines? ;( TTC is rough. I wish you all baby dust. Hopefully we all get our bundle of joy soon!
