Should I be afraid ?

I am currently 6wks1dy. I have been to the ER 2 times since I found out on the 20th. I have been to my OB once on an emergency. When I went to the emergency room on the 28th they said they saw two fluid pulls, I went to my OB later that day and they said I have two gestational sacs(twins). On Friday I passed a very small blood clot, no pain and no bleeding or pain since then. My doctor told me to just rest unless the bleeding got worse and pain started. Today I woke up not really feeling pregnant. I’m trying not to stress but I’m not sure what to do. With my daughter I was always throwing up due to hyperemesis being so severe for me. I’ve already lost like 9lbs and idk if that’s normal. I really feel alone in these thoughts.
