worried

Jessica
So. I'm really worried and need some input here to kinda calm my nerves until a doctors office is open..  I've had a miscarriage, almost 2 years ago.. I have now missed my period but 5-6 days. Which is very rare. My are always spot on. 
I've had morning sickness And now I've started cramping really bad throughout the day.. I've taken 2 pregnancy test and both came back negative. But I still haven't received my period..
Please no negative comments, I will block you.
Just looking for some Guideness here.
