Ectopic pregnancies

I went to the obgyn yesterday at 4 weeks 6 days. That morning I felt faint and extremely anxious. It was like my body was forcing me to be anxious. I wasn’t worried I thought maybe it was just my cyst causing the pain. I ended up almost fainting before the doctor came to see me. A nurse help me calm down from my panic attack. I’ve had 4 miscarriages and at this point they don’t scare me. I feel sadness and grief but never fear. So it was extremely weird for me. I got a transvaginal scan and they saw a thickening of the lining but nothing else. Obviously she prepared me for the possibilities, too early, ectopic or miscarriage. She ordered the blood work that day but I was too weak to get it done. I went this morning and results came back at 2206. She messaged me and said it was a good number but the most important is the next number if it doubles or if it’s slowly rising. I’m not sure because of feeling anxious hormonally is making me feel like something is wrong and it’s all in my head or if my body is trying to tell me there is something wrong. Either way… I am scared now.
