Bleeding with rising hcg

I did a pregnancy test after missed period it was positive. At 5 weeks I started bleeding. It was similar to my period. Not more, not less I would say. My obgyn asked me to come in for hcg test. I went in a week after I started bleeding so week 6 and my levels were 189. She asked me to back again a week later. My levels went up to something in the 1000s I don’t remember what she said. She’s asking me to come back for another test 48h after that test. That’s tomorrow. I’ve been having very very slight spotting the past few days. My mind is spinning. I’m so worried about an ectopic pregnancy. Anyone been through something similar?
