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 don't 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.. I'm scared to check it again now... Is it possible that i'm pregnant since i take 2 packet (4 tablet of Postinor-2) in a month? thanks alot..
