Does bleeding after ipill whether with clots or not confirms that you are not pregnant? How can we know it is withdrawal bleeding if they come at same day of expected date ? Does everyone has withdrawal bleeding or are there any exceptions ? If I had ipill 2 times at 17 and 25 of a month and my expected date is 28 and bleeding occurs at 29 how can I know it is withdrawal bleeding or menstrual bleeding? How can we know pill worked?
