Possible miscarriage

I went to the ER last night due to bleeding at around 5 weeks pregnant, they drew blood my number was a 45 they pretty much couldn’t rule out anything because I’m so early & have no clue how far along I truly am as I had a loss last month & haven’t tracked anything. The bleeding has been the exact same since yesterday(moderate) I have zero pains. My question is should i get a second opinion? Is it worth it?
