What can i do

Yesterday i posted about possible miscarriage at 10 weeks because of my levels dropping. Iv still had a few cramps and still only spotting when i wipe. I keep getting headaches. I’m so uneasy i just want to know what’s going on. They told me to wait until my scheduled ultrasound on Monday but idk if i can wait that long. I want to know if my baby is okay or not 😔 , would it be okay to go to the ER just to see what they tell me there?
