is very effective emergency pill if taken within 72 hrs of unprotected intercourse
.The sooner you take it, the better your chances for success.The 2 tabs treatment can prevent a pregnancy. With this pill,pregnancy rate
After taking the pill,a withdrawal bleeding occurs within 7 days or delayed....that is quite normal. In case of torn condom,you may take Plan B
So don't worry about the thing happened and wait for next period (may be early/delayed) and if missed,take a home pregnancy test after 7 days.If positive,consult with your gynaecologist.
All the best. For further suggestion,you may mail me....my Id: firstname.lastname@example.org
