discharging 4 days before period??

so i was combing my hair in the bathroom , then i felt something coming out of my vagina... I thought i started my period but no it was clear white discharge. 😧 i feel alittle cramping too but its too early to be feeling like this since my period doesn't start in 4 more days?  And i never discharge this time only on my fertile days which past already 😧🙏
