I have taken prostinor 2 after 53 hours of unprotected intercourse, however, I did not bleed as stated in the instruction , my boyfriend just put his penis' head in my vagina which is around 2cm to 5 cm deep into me , we were worried about the pre *** and took the pills as instructed, its been 3 days since I took it and I have headache and stomachache after consuming but the bleeding doesn't occur so is it normal or I am pregnant? I do drink cold beverages will it affect it?

Of course prostinor 2 or any of the morning after pills are not 100 percent effective, I am sure you know that. And you also know I am sure the longer you wait after sex to take the pills they are less effective. 53 hours is not a good as 5 hours or 30 hours.

See if you may have bleeding within the next week. And the other issue is it can effect your normal period cycle for a month or two. But you will need to wait now till the normal time for your period and see if you miss it or not. If you miss it, wait till the next week and try a home pregnancy test.
