I had unprotected sex with my GF 8 days(11 feb) ago then immdetiely she took emergency contraceptive pill. 2 days(17 feb) ago again we have a protected sex but i had doubt if condom fails. so in this condition what should i do? i should gave her a emergency contraceptive pill again or any other pill? because she delayed her periods by 5 days (her periods date is 14 feb).
