Hello and welcome to ‘Ask A Doctor’ service.

I have reviewed your query and here is my advice.

Since your pregnancy test is negative, you should relax. Unwanted 72 is a post coital emergency contraceptive pill. It prevents pregnancy if it is taken within 72 hours of the unprotected sex. It has got following after effects:

1. Few days after taking the pill, there may be little bleeding for a day or two. This does not require any medical attention.

2. The following period may get delayed by few days to a week or so. If the pregnancy test has confirmed non-pregnant state, it is safe to wait for a week expectantly for the menses to appear.

Even after a week, if you do not get menses, then repeat the pregnancy test on overnight early morning first urine sample. If it is still negative, some progesterone preparation for 5 days will get you withdrawal bleeding within 4 to 7 days after that. However, these pills should be taken only with a gynecologist's advice.

Hope I have answered your query and this clarifies your doubts.

Regards,
Dr. Nishikant Shrotri
