Thanks for writing to HCM
Your previous USG didn't mentioned whether there was fetal pole
seen or not inside G-sac.
As you have spotting right now, Ultrasound
should be done to find out whether there is any fetal pole or not.
Treatment will depend upon USG findings.
If fetal pole is seen then follow up USG should be done.
If fetal pole is not seen then it is considered as blighted ovum
and treat it accordingly.
Get well soon.
