1 week late

Hannah • Elias ❤️
I am one week late for my period as of today. I took a pregnancy test yesterday that came out negative. How long do I wait to do another if I don't get my period this week? I had unprotected sex 3 x the last time I ovulated. 
My sister and I always have the same cycle but she already started and finished hers, which brought it fully to my attention. 
I used a CB digital test, should I use FR? Wait a few days? A week?
