Confused..help!!

I’m so confused this was my vfl yesterday morning

And this is my BFN from this morning

I had some light brown spotting yesterday but it stopped very quickly. Has this happened to anyone where you get a bfp and then a bfn?? Were you still pregnant?? I was so excited and now I don’t know what to believe. 😞 We have been trying for a year and I am 4 days late for AF!
