15 week 3 days ... HCG levels dropping

AS • Mommy to a beautiful daughter and 2 handsome sons 🥰💕😍💙

I went to the ER on 11/1 then again on 11/4 , yesterday I was bleeding so I went to ER to get checked , looks like my levels dropped could it mean I will be miscarrying . Yesterday US they couldn’t find cause of bleeding and said baby looked fine but also from 11/1 to 11/4 seems like the HB dropped some

Update : went to see My OB today and they sent me to my high risk doctor and they couldn’t fond cause of bleeding , they think it could have been a blood clot , baby was measuring perfect and heart rate was still nice and strong as of right now they aren’t worried about anything , was just told if bleeding comes back to go to ER again
