Hopeless 😔

So on Friday (6-10) I took a Clearblue weeks estimator. It read Pregnant 2-3. At this point I've read that my levels had to AT LEAST be 200. I haven't had symptoms in about a week so I asked the doctor to do a HCG count. Today (6-14), the HCG count is 397 and I should be 5 weeks 1 day. The numbers should have doubled and doubled again right? I haven't had any bleeding yet, but I'm sure I'm miscarrying for a second time in 5 months 😔😔😔 I'm going back on Friday to have my levels tested once more. anyone have any experience with this or opinions?
