Thanks for query,
Your sexual act taken place in fertile period.
Have you taken primoult N after your sex?If yes then it is still continued.? stop it first.
Ideally you should take after pill within 72 hours of act.as you have not mention the dates? If already 72 hours passed there is no after pill works.
You should wait till you complete your 34 days from last cycle.then take pregnancy
test if it is negative then take any birth control pill daily 1=1 for 3 days then after 4=6 days you will get withdrawal bleed.
