Period still hasnt shown but Test says negative!? So confused!! PLEASE answer!!? - no period, negative pregnancy test, bloody muscus

Hello All
My time is now 5 days late (this is very different from me, I swelled my time on the clock) and IM a lot, I get a feeling of nausea and a taste of blood in his mouth was morning (3 times before and pregnant lost 2), so I recognize the signs of a diploma. But I have a pregnancy test at home tonight doing and it was negative, I've never been before.

Anyone else been in this situation, I do not think that it is too early to show a positive test (If I) recommendations, is very much appreciated, 10 points for best answer, thank you in advance for your reply
