Hi welcome to health care magic....
I can understand your concern....
Let me know you for exact dating of
pregnancy and to exclude ectopic pregnancy first USG is must ....
If pregnancy is within 9 week as you giving history of around 4 week than
abortion can be done medically or vaccum aspiration...
Suction evacuation will also be good option..
For medical termination two tablet taken available as
mtp kit .
Day 1 : mifepristone 600 mg orally
Day 3 :
Misoprostol 800 ug vaginally
After taking misoprostol bleeding will start within 6 hour and in 4 to 5 days abortion completed ...
But this should be done under strict medical observation of gynecologist ...
After taking these tablets each time for few hours breast feeding not to be done ...
Take care
