Me and my partner have sexual intercourse 2 weeks before my periods and I had taken i pill within 72hrs but I skip my period which was 11th January till now 16th January I didn't get my period. Today morning I take the urine pregnancy test which shows me positive. Can I use avort kit (combipack of mifepristone and misoprostol)  to avoid my pregnancy as it is in early stage. If yes then how can I use the kit to give best results to avoid pregnancy. Please help me with this.
