Hi. Kindly help out here. I had unprotected sex with my girlfriend on 14th Oct (5th day of her cycle, after her periods) She took postinor 2 20 hours later and the second pill after 12 hours. On 18th (three days later) she had bleeding which got heavy on 19th and light on 20th. On 21st, it was just light spotting. The days that followed she had nausea at times. Her period was due on 5th November, but is now late for 5 days. She has some cramping but no periods. What are the chances she could be pregnant?
