Thanks for the query.
The bleeding you had after taking the pill could be because of the menstrual irregularity caused by the emergency pill.
The discharge can be due to some vaginal infection
So you better consult gynecologist, get examined to find out the actual nature of the discharge and take treatment accordingly.
Both you and your partner should get treated simultaneously.
