Hello Doctor, About a week ago, my girlfriend missed her (padmini) birth control pill one night and we had unprotected intercourse the same night. However she took the pill when she remembered the next morning. She gets her period about 28 days. Today is the 30th day and she still hasn't got her period. There was no emergency contraception taken. Is it likely she could get pregnant from that or is there any other measure for this situation. Thank you.
