Feeling crappy

Hello ladies! Feeling. Nothing but miserable. Went home early today from work with abdominal pain(epigastric not uterine pain) I was told I wasdehydrated  and needed some rest. Got home today and for the first in a long time had some bleeding, old, brown. Unsure how to feel about this.... and I hope my baby is ok. My US appt is next Thursday. Going to stay home and rest tomorrow... 😓
