VFL for days now!!!

Michaela • TTC our rainbow baby ❤️🌈💜
Hey ladies, so I think I'm about to loose it! Af was due 1st March and still hasn't shown so I took a HPT 4 days ago (afternoon wee) and I got a VFL. I tested again this afternoon and it's still faint. Into the bargain, I got a big 'Not Pregnant' on a clear blue digital. I had a miscarriage November last year and my cycles have been all over the place, so when I say af was due 1st March, that's as best my guess could be! I am really hoping these little faint lines mean I ovulated later than I thought, and it's just too early for strong results. This is the afternoons test, I'm bad I know for not waiting till the morning but there's no way I couldn't pee on that stick as soon as I got home!!! What do you think??? We are desperate for our rainbow baby ❤️🌈
