Don't know what to do. ..

Tested on Wednesday 12 dpo and got a very faint BFP. AF due today woke up and sure enough here she is...what is going on?? Miscarriage?? Told hubby about the BFP and how I started AF today and he brushed it off and kept watching TV..no emotiom whatsoever. Not even "are you ok?" Ugh....I'm so upset, I just want to punch him in the face and cry...Sorry girls but I had to vent 😢😢😭
