Hello, Thanks for writing to us. I suggest you to undergo one home pregnancy test at the earliest to rule out pregnancy. If you did sex in the last week of period cycle, then chance of pregnancy will be quite LOW. On POSITIVE test, medical abortion should be done with abortion pills. However, it is not recommended at home without doctor s prescription and guidance. For proper dosing and direction of using those pills, you need to consult with local doctor, which will be helpful also in emergency. It can be done up to 9 wk safely by using abortion pills (Tab Misoprostol and Tab Mifepristone, present in MTP Kit) under observation or guidance of gynecologist as it may cause unnecessary excessive vaginal bleeding, abdominal pain etc and may require surgical method (D & C) to complete abortion. Don t take those pills by yourself. If you get NEGATIVE test, then I can suggest Norethisterone pill for 5 days to induce period. You will get period within 5-7 days. Practice safe sex and use emergency pill or condom to avoid unwanted pregnancy in future. Good luck.
