Medical abortion is safe with a high success rate if done before 9 weeks of pregnancy.
However, in 5% of cases, there may be incomplete abortion and heavy bleeding requiring hospital admission and surgical management.
So it's very important that you do medical abortion following proper protocol and in guidance of a local gynaecologist who can take care and manage in case of emergency.
Get ultrasound done
Don't take oral pills for more than a year at a stretch
It's right to know about after effects of pills when the woman is wanting a baby
The effects of hormones present in the pills take sometime, maybe few months to wane
But pregnancy is not affected if other reasons are not present.
Anytime when termination of pregnancy is done by mifepristone+ misoprostol (which are contents of contrapill) confirmation of complete abortion must be done by ultrasonography 14 days after treatment whatever may be amount of bleeding.
