Hi My wife had taken 18days pills out of 21 days pills kits  for avoiding pregnancy/ and delay the periods  , We had unprotected sex on 18 th day of her pills and she stopped after that , she had taken a contraceptive pill on 47th hours after that   , and she is supposed to get the periods on 24- 28 after stopping the 21 days pills kit. Please advice what are fair chances of she getting pregnant ?? when possible she can test for it?? or  does she has a chance of getting ovulation after taking 18 days pills continuously ??? Appreciate your help here..
