On 11th of September me and my partner was having intercourse around 2-3pm all of the suddenly the protection got broke somehow i didn't ejaculate we stopped there and after that we didn't have intercourse she had her periods last month 18th of August. Which means its one week before her periods i guess so she took an ECP (unwanted 72 single does of .75mg) within 24hrs to be exact its almost 20hrs. Just because we wanted to prevent the pregnancy to be a safer side she took am ECP. My question is there any chances she will get pregnant, when she can expect her periods since its one week before her periods to come. Does she needs to take another dose of unwanted 72 cause it has 0.75mg where as ipill comes with 1.5mg. and if she gets her periods that means she is not pregnant?
