What's going on?

Rainbow

Ok so I had a different post but accidently deleted it when trying to update. I've had spotting since Wed. My spotting has continued and seems to be getting heavier. Its mainly noticeable when I wipe or use the b.room (bright red). On Wed. (6/27) hcg @2300; only sac on u/s. Thurs. (6/28) levels @2738. Fri. (6/29) bleeding almost gone. Sat. (6/30) bleeding was mild. I ended up in E.R my hcg 3thousand and some. Had another u/s still couldn't see a baby. I should be 7 weeks by now. Now they're thinking it's ectopic. I was put on complete bedrest until I see my dr on Monday or Tuesday. I'm so scared, confused, sad, just plain emotional. Idk what's going on. Dr's dont know why I'm bleeding. They called my OB last night and he told them to let me go home, and that hcg levels aren't always to go by. I have mild cramping as well. Idk what to think anymore. 😞 Please if this has happened to anyone what was your outcome? I'm expecting the worst and prepared for a miscarriage.
