My friend is 20 years old. After having unprotected sex on April 14, she took Unwanted - 72 pill after four hours. Her periods expected date was 28 April but it's delayed by 19 days. Is there any chance of getting pregnant? Or when she can get her periods because she took pill after 4 hours so it's too early she took pill and doesn't seems having chance of pregnancy but delaying in periods making it difficult to understand. Can you suggest us something on this issue?
