Hi... i had my last period on Nov 9th.. then i did succesfull sexual intercourse on Nov 24th.. then i took Postinor-2 2 tablet in a time.. after that we did it using condom.. but about 3-4 days later, we did it again without condom and 1 day after i took postinor-2 again, 2 tablet in a time... But until now (December 19th) i dont have my period yet.. My period is usually unregular..It comes every month, but not in exactly same period...The cycle can be 30,32,36,36,38 or even 40 days... I worried because today is 40 days already since my last period.. Now i feel little bit nausea...i checked Presumptive Pregnancy test (Test Pack) last week.. Blurred line...I repeated 1 day after, it showed the same result..Not positive,but also not sure negative.. Im scared to check it again now... Is it possible that im pregnant since i take 2 packet (4 tablet of Postinor-2) in a month? thanks alot..

Hi, Welcome to Chat Doctor. I am Chat Doctor. I will be answering your concerns today. Postinor 2 if taken within 24 hours of unprotected sex is 95% effective in preventing pregnancy. You did delay in taking Posting 2 the second time. So there is a possibility of pregnancy. The pregnancy line blurred or sharp, does indicate pregnancy. I hope you are doing the test properly. I suggest you repeat the test either with early morning urine sample or do a blood pregnancy test which is more reliable. I hope this is helpful. Best wishes, Chat Doctor.
