I had sex with my gf on the 4th of December 2014 which was her 9th day 5th or 6th day after her November period. She used postinor 2 within the first 2hours as a single dose. 6 days after she had virginal bleeding for 3 days. And it stopped. Question, to what percentage was she save- I mean, could she be pregnant till now, she hasn't seen her period.
NB: She used the postinor 2 again 2days after the first unprotected sex.
