Hi, we had sex on November 21, 2011. Due to contraceptive malfunctioning she had to take an emergency contraceptive pill (i pill from cipla in India). To add on the first pill she took was with coca cola instead of water which hence dissolved in her mouth instantly. We realised after searching on net that emergency contraceptive pills dissolve in coke and may be less effective. So just to confirm she took another pill too. Both pills were taken within 12 hours of sex. On December 26, 2011 she did an home pregnancy test and it was negative. But she still hadn't had periods. Her last periods were from 17-20 November, 2011. Please help ! Is she pregnant and should we go for a blood test or what is wrong?
