5weeks 2 days

I been spotting for the last past week ...Not really heavy ... but I believe it's because of stress. I been doing a lot of screaming at my fiance and the kids. I went to the doctor office yesterday and they comfim that I was pregnant with a pregnancy test which I already took two last week when I missed my cycle. The doctor told me to go to the emergency room if I was spotting ... I went to the ER last night and they gave me another pregnancy test which showed positive. So they ran blood and gave me two types of ultra sounds. The results came back that my hormone level wasn't high enough and they couldn't see a baby . They told me to come back Friday when I Should be 6 weeks to see if I miscarriage ..or if I am miscarriaging. I'm wondering is it possible for my baby to be to small to really detect???
