Hello dear I understand your concern You are on primolut N to delayed period since last week. If you did sex when you are on primout N then it itself act as contraception and prevent pregnancy. But if you did sex before starting primout N and during fertile phase of period then there is chance of pregnancy. If period will not occur 7 days after stopping primout N then go for urine pregnancy test and or blood HCG test to confirm pregnancy. Avoid stress, take health diet, drink plenty of water, do regular exercise Hope this may help you Contact further if follow up needed Best regards Dr. Sagar
