Period

Steffanie • “Do you look both ways when you cross my mind?” 🙃
So I'm on the pill (I believe it's the combination pills) and I'm 5 days late on my period... I've been sexually active but I have been using protection and I've even taken like 3 different pregnancy test and they all came back negative. Should I be worried about my period being almost a week last or should I just chill out and wait to see if it comes later this month...?
