thanks for the query.
It would be better if you had mentioned your gestational age
Anyways, if you have not passed any fleshy mass- less likely you had complete abortion
Moreover the protocol of cytotic which you are taking is also not right.
What i suggest you is to get an USG done to know the gestational age.
This also helps weather you need medical or surgical line of treatment.
Please don't take medicines on your own as it has lot of side effect.
Consult your doctor immediately.
Hope this helps,
