I need to get my period but it isn't here yet. Help!

IY

I'm on the pill. Take it every day on the same time. Never had any problems with it. I had sex a week ago and yesterday. Yesterday evening i had bad cramps just how it's supposed to go but this morning it wasn't there yet. I feel that i need to get my period but i'm just stressed because it's a bit late. Calm my nerves please 😶
