Me and my girlfriend had unprotected sex on the last day of her period. Just to be sure she took an ipill the very next day and got some bleeding about 4 days later, which I am given to understand is withdrawal bleeding. It has been a month and she has no signs of pregnancy and we're expecting her to have a period soon. Is withdrawal bleeding a sign that the pill worked and she can't be
pregnant? And for how long can the periods get delayed now?
The timing of the intercourse was safe and we even used an emergency contraceptive, with a sign that indicates that the process was effective. So I should not be worrying even if the periods get delayed ?
