point 1. from when is this 20 days cont? when did yo have sex?
if you have sex between the 13 th day ( cont from the first dat of your last period) to 21st day your chances are much more.....
as you say that it has been 20 days by now it is difficult for the doctor to say that. if you are not planning to get pregnant now simple just eat lots of ( minimum 2 or 3 full) poppy fruit per day for 4 to 5 days. Just enough things will be cleared. you should anti pills immediately. ok no problem now just eat lots of ( minimum 2 or 3 full) poppy fruit per day for 4 to 5 days.
