Ultrasound inconclusive at 5w 4 days high hcg
So I am 5w4days pregnant, I tested positive on 9-10dpo and had mild cramps hear and there. Today i started to spot brown/pinkish discharge, called OB office since i had a miscarriage last year. I went to emergency and they did ultrasound (I asked them abdominal as my last loss started soon after tVS) the result came as inconclusive, doctor said no sac is seen and hcg was above 10000. I’m really worried now, has anyone gone through anything similar ?
