Hi thanks for your question.
You had taken one tablet of miferistone 200mg,that is right but after that you had taken one tablet of misoprostol
200mg vaginally that is wrong.You should have taken all the 4 tablets that is total 800 mg of misoprostol vaginally.Since bleeding has occured after a total of three tablets.I would suggest you to go of ultrasound
to confirm complete abortion
has taken place or not.If abortion is not complete you have to get it complete by saurgical means that is D & C, for which you need to consult a gynaecologist.
Hope this answers your question.
