Brief Answer:
possible side effect of unwanted 72 itself.

Detailed Answer:
Hello,
thanks for the query to HCM,
After taking UNWANTED 72 within 24 hrs of protected intercourse, which was actually not required , you should have got a withdrawal bleeding in next 5-7 days and if you did then the day 1 of that withdrawal bleed shall become day 1 of your fresh cycle and accordingly your next menses shall be scheduled after a month.
But if there was no bleeding after the pill intake then you should get a serum beta hcg test done to rule out pregnancy conclusively as urine pregnancy test is not conclusive until 8 days post missed periods. If the beta hcg test is negative then this is a side effect of unwanted 72 , which is common on first time use causing delayed menses.
