Last period date: 10aug-15aug. Had unprotected sex on 27th aug. And had ipill (ecp) 6 hours after the intercourse for the first time in her life. After four days on 1st September she started bleeding. The pain and blood was just like her periods. Bleeding continued for 3 days and stopped on the fourth day. Yesterday i.e:18th September, she did a test with prega news pregnancy kit which came negative. My question is that every thing fine? Do we still have to worry about pregnancy. We are tensed. please help.
