Hello,
I have gone through the query and understood your concern. Since you have taken the emergency pill, your hormone balance will be disturbed and your next natural period may get delayed by a week or two. You may have to wait for a couple of cycles to regularize and then go for your trial for conception. In the first place, you did not need any emergency pill since you were in the safe period during the intercourse. Please note that ovulation occurs two weeks prior to the onset of the next period in a normal cycle and this is the fertile period for conception to occur. Regular intercourse during this period gives good results. Hope this helps.
