Welcome to the ehealthforum and I am glad to help you out.

If your normal expected periods were on 12th April and you had intercourse on 8th April which is on 26th day of menstrual cycle, chances of pregnancy are less. However if there is a history of any intercourse prior to this date close to ovulation which occurs on 14th day of menstrual cycle then chances of pregnancy are there.

The delaying in periods can be due to hormonal effect caused by the emergency contraceptive pill also which you had taken 12 hours after intercourse. This is due to high levels of hormones in the post coital pills.

If you are apprehensive regarding the status of your pregnancy you can get it checked. The test can be positive and should be done anywhere from about 2-3 days prior to a missed menses to 4-5 days after, but usually it should be done 7-10 days past your missed period.

Otherwise you can get a serum HCG also done which is more specific than urine pregnancy test.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and regards.
