Pregnancy Worries after having unprotected sex

Patient: My wife’s periods ends on 16th February 2015 and we had unprotected sex on 18th February 2015 . Would there is chance of getting pregnant? Should she take I-PILL? Please advice

Doctor: Hello,Thanks for the query.If she ended her menses on 16th February and you had sex on 18th, then she was still in her safe period and ovulation had not occurred making her pregnancy safe. Hence, an I pill is not required.Hope this answered your query.Regards
