What should a girl do if semen is discharged while she is at university, and she cannot perform ghusl until the time for another prayer has begun?

A woman must perform ghusl (ritual bath) if she is certain that what was discharged is semen, which necessitates ghusl. If she is unable to perform ghusl due to the unavailability of a suitable place, and she fears that the prayer time will expire, she should perform tayammum (dry ablution) and pray.
