If you do not want to continue this
pregnancy, you can very safely terminate this pregnancy. The safe limit for termination of pregnancy by medicines is 9 weeks of pregnancy.
However, after that there are other methods of termination of pregnancy like suction evacuation. Once 10 weeks are crossed, suction evacuation also does not remain safe. In such cases, dilatation and evacuation is the best way till 12 weeks of pregnancy.
After 12 weeks of pregnancy, the termination is rather prolonged procedure. By use of
prostaglandins, these pregnancies can be terminated, however, it takes time for completion of
abortion.
There are some Obstetricians who perform termination by medicines even after 9 weeks however, in those cases, I would not prefer that way.
I would advise you to rush to the obstetrician and get the termination done if you do not want this pregnancy.
