I had a protected intercoursewud my husband on 18 th and 19of this month .my LMP was 3 rdjanuary and later I realise that the days fall on the fertile period. Since we married last 3 months back against family wish we don't want a baby now.
As per LMP today is my 27th day. So as to induceabortion(if any) I had misoprostal tablet 50 mg
But still didn't get periods
Am I pregnant

You don't know if you were ever pregnant to start with and it is too early to test to even know if you are pregnant or not.

You have to wait two weeks past the missed period. And test with first urine of the morning.

Next I will assume you are guessing at your fertile time or using some silly online chart, The only way to actually known fertile time is though measurement of body temp
