So much Anxiety

So I’m 7w4d pregnant and I went at 5 weeks for a scan and they saw a gestational sac but no yolk sac yet. Ever since then I’ve been so worried it’s s blighted ovum. My HCG at that point was over 5000 and the trend went from 225-875-5100. I have not had a scan since then but am nauseous and have sore breasts but in the last week my symptoms have lessened. I have had no bleeding. Am I just being paranoid??
