PLEASE I NEED ADVICE SO SCARED

Amber

Found out i was pregnant 3/30 the next day i started spotting pink. Then 4/1 started bleeding dark red blood slightly lighter than a period not filling up a pad though i had slight cramps went to the ER they took my blood HCG level was at 16. They told me come back in two days. So today went back they called and told me my level went down to 11.5 but we got disconnected. I currently have no bleeding or cramps just some brown discharge. Any body experience this and have a healthy pregnancy I’m still very early on about 4w4d. Please even if it’s similar anything will help.
