Hi doctor my girlfriend's last period date was 23rd March and we did sex on 3rd of april and took unwanted 72 within 2 hrs of unprotected sex, since 14th april she had cramps,headache and all natural symptoms of periods but she was not getting her periods as due date of her period was 19th april. She did the
pregnancy test today morning and it was negative. Kindly tell us what to do in that situation?
