Welcome to HCM.
You have taken MT pill with Misoprost 200 at the time of 6 wk gestation and likely one month ago. It is observed that 85-90 % chance of complete abortion occurs with using those medicine with gestational age
up to maximum 8-9 wks.
Your USG scan shows INCOMPLETE ABORTION
You may try MIFEPRISTONE tab 600 mg single dose for complete abortion before undergoing to surgical procedure.
But at this stage, best option is D &E (short surgical procedure to evacuate intrauterine conception) ,if medical abortion
fails. It also reduces unnecessary excessive bleeding.
So consult with your doctor regarding the procedure.
Be well and maintain personal hygiene.
