Medical obortion at 5 week 5 days.

Hi sir/mam I have 2:6 years daughter and I had been tested positive pregnancy, later both husband and wife decided to drop pregnancy. As doctor suggested had given Mifepristone and Misoprostol combination tablet. After taking Mefipristone 24 hrs I have firstly passed tissue and blood clots, not too much big lemon size tissue but it was some size of tissue.... And than started normal periods first 3 days soaked two pads in a day and night 1 pad.. Later 5th normally day and night 1 pad soaked... Now 9th day no spotting and it's 10 th very light spotting still continuing..there is no stomach pain, fever or any kind of problem..im feeling normal....Is pregnancy successfully dropped??? And I have not done ultrasound, should I have to take ultra sound?? Even when light spotting ultrasound will be taken or I have to go for ultrasound after stopping completely... Please suggest. Than you for helping in advance.
