I had an intercourse on the 6th of April, 2016. I took Unwanted 72, the contraceptive, just after 15 minutes of intercourse. I got my periods on the 10th of April, 2016, i.e., after 4 days of the intercourse. My actual date of periods is 25th or 26th of every month. I had my periods this month and I as far as I am concerned, it might be a side effect of the contraceptive. Now I have not got my periods and I'm 4 days late. Is there any chance that my date of getting periods has changed or am I
pregnant? Shall I wait till the 10th of May, 2016, in order to get my periods? What are the chances of me being pregnant?
