Hello doctors, I had unprotected sex with my girlfriend on 23rd september and she had just finished her periods on 19th September. We consumed an ipill after around 12 hours of intercourse. On 1st Aug  she faced some bleeding which ended around 2 days. What will be the next date of her periods.? And are there chances of pregnancy.? Moreover till now she has no single symptom of pregnancy..and is completely alright even after 1 month of intercourse. Can she be pregnant or it is ruled out? Please help.
