I have a newly married friend. The couple had sex with protection but her husband entered once without using protection though he didn't ejaculate. Still she took an emergency pill to avoid pregnancy. After two days they repeat the same thing that I stated above. Now she is confused that should she take a pill again or the previous pill is still working? Actually, she wants to know that if her husband enters her without putting on condom and doesn't ejaculate, is there any chance to get
pregnant? Well, 72 hours have passed since they intercoursed this way. Is she in danger?
And for how many days an emergency pill works?
