Thanks for the query.
Before going to medical abortion
you have to consult gynecologist and undergo ultrasound
once to rule out the possibility of ectopic pregnancy
If the intrauterine pregnancy is confirmed then with her advice you can go for medical abortion.
The companies you mentioned are good companies only.
But with any brand some complications like pain abdomen, nausea
etc can be seen.
After taking tablets for medical abortion the process will complete in around 48 hours usually.
If you have severe bleeding better to consult your doctor to rule out the possibility of retained products.
