Pregnancy of unknown location

Jordan

Made 7 weeks today and was released from the emergency room for some slight bleeding and pelvic pain gof blood drawn and an ultrasound for the results to be that they seen 3 circles and couldn't detected a baby so they call it pregnancy of unknown location which could lead to a miscarriage. Any thoughts or anything to help understand better this is my 2nd pregnancy the first one was just one baby which I carried full term no complications and she is 7 now
