Spotting at the early stage is not uncommon. Many are due to implantation
bleeding and will not result in miscarriage.
I had spotting at around 6wk, and the nurse told me to rest as much as
possible and keep activities low. An ultrasound right away may not tell much
if you are in very early stage (<8wks). I did an ultrasound the second day
after I called the OB office, but the technician can't see the heartbeat (
the baby were almost 2wks smaller than the prediction based on my last
period). So I had to come back a week later to repeat the exam, while
worrying about the baby for the whole week. Luckily things turned out to be
fine for me.
You do want to be alerted and call your OB immediately if the bleeding gets
heavy, and/or with severe abdominal pain.
