HCG possible miscarriage


A weeks go I was told my hcg levels dropped from 7800 to 7500 they told me I was miscarrying but I still feel pregnant and I haven’t started bleeding or cramping at all. They did an ultrasound a week an a half ago and all they could see was a sac and I was only about 4 weeks then. This will be my 4th miscarriage in just over a year we had so much hope for this baby but I’ve been told to not lose hope that they could go back up that they didn’t drop much but they aren’t checking my hcg levels until Wednesday so I’m stressing I just want to know.
