My sis(17 y) had unprotected sex only once on 3 or 4 Dec last year. She then took ECP(72 hours) within 6 hrs. Then she suffered cramping, back-pain and vaginal pain. When she didn't get her periods near 8th, she took HCG test and got +ve results two times. But then she got her bleeding by 11 or 12. They were resembling the periods.. #The next month she got her bleeding on 10 or 11.# But now, either or she didn't get them the third time.
Can she be pregnant? Please help! I'm stuck
