Hi, My wife took ipill after unprotected sex and she got her periods on October 5th, but the bleeding extended for 4 more days than as usual. Then we had unprotected sex on 21st October. but withdrawn before getting ejaculated, still have a doubt since the expected periods to be started on Nov 2 did not occurred. The pregnancy test done on 7th and 11th november gave -ve results. Is there anything to worry as we dont want a pregnancy now.
