Hi again

It may have been the medication that lightened her period. 

The sign that the drug was effective is that she doesn't become pregnant. Some women bleed 3-7 days after taking this drug, some don't. There are no definitive answers to your question, as each woman is different. 

As I said, her risk is very, very low.  That's all anyone can tell you.

Hi zuboy

Having sex on the first day of a period rarely ends in pregnancy but since she took emergency contraception, her risk is even lower. The medication is up to 95% effective.
