Bleeding! No cramps though

Abigail
Went to ER last nite since i had Brown discharge, they tested my blood, urine, and did ultrasound. Heard baby heart beat baby looked ok so they just told me to get rest and drunk water. Didnt get out of bed at all today and when i did i felt this gush and thought i peed myself. I was bleeding(bright red) im not having any cramps, i still feel very náuseas tho, have been all day like normal. Help?! Anybody bled like this and baby still be ok?
