Possible miscarriage 😓

Jordan

So I’m unsure if I’m having a miscarriage? I’ve had Several positive pregnancy test! But I’ve been bleeding & when I went to the er a few days ago my hcg was at a 88.0 & nothing could be seen on the transvaginal sono when they tried to do one , Since then I went to my ob for blood hcg redraw on Friday morning to check to see if my levels are rising or lowering. I won’t know the results until tomorrow or Tuesday… this would be my 3rd pregnancy, I already have 2 living kids & have never experienced this… I have never had a miscarriage or possible miscarriage so I have no idea what to expect?? I have not had any clotting or haven’t passed anything or haven’t had any type of pain
