Does hcg linger for a week and a half after supposed miscarriage?

I got a positive pregnancy test March 15th, the day my period would’ve been due. I had been testing and they were all negative literally until the 15th which were faint. Pretty sure I ovulated March 2n-March 4th. Went for MD appt March 24th where they did pap, hcg levels and vaginal ultrasound. Didn’t see anything on vaginal ultrasound, MD immediately placed me under ectopic pregnancy precautions and said it COULDVE just been too early to visualize anything at 5 weeks. Started some light bleeding at 2pm Saturday that lasted till roughly Monday morning. It wasn’t heavy at all. No pain. Went to the ED per OB. They also did hcg that increased from 43 to 55 in the 2 days and another vaginal ultrasound which showed nothing. One small clot passed came out when she did the ultrasound. Took me back to the ED room and said it’s most likely a miscarriage. Im like okay whatever, it’s not ectopic. Whew hopefully no tubes will be lost. I move on and follow up with OB a week later for more hcg blood draw. Went up to 58. They messaged me a few days later to say complete another vaginal ultrasound. Im just over everything at this point. I’ve had no pain, no bleeding, pregnancy symptoms are rampaging. I feel the symptoms are getting worse. I’ve been hot flashing like crazy, extreme hunger, and plenty of nausea. I took 3 different tests a week and a half passed this said miscarriage diagnosis and got this. I didn’t even get a positive digital initially when I took the hpt. I’m so paranoid now wondering if this is a mis-diagnosis because I drank wine just about everyday after they said there’s nothing visible on the vaginal ultrasound and it’s a miscarriage in the ED.

I’ve been pregnant 3 other times. Bled with all 3 others which threw me off because I took it as a period until I realized it was shorter and lighter than usual. One is living and I terminated the other 2. One was the chemical with the pills which caused a miscarriage so I felt what a miscarriage I thought would feel like. The bleeding was pretty heavy like a period with cramping and I saw the tissue pass and pregnancy symptoms stopped immediately and that was at 5ish weeks as well. None of that happened this time around.

I will also say my OBs never took hcg levels before. Only urine tests to confirm then follow ups at 8-9 weeks unless there was an emergency.

So maybe hcg levels are just tapering? I’m just so confused. I don’t even want to go back to the doctor.
