My wife & I had unprotected sex in the afternoon she took a contraceptive pill after an hour.After 2 days she started to experience pain in the lower abdomen after that white liquid would come out from her vagina..it went on for 4-5 days but abdominal pain has gone now so is the white liquid and again on 8th day after pill she felt dizzy just a bit maybe because of weakness but not sure. is there any chance that she might be pregnant.her periods are due in another 7 days..
