Not sure if I’m pregnant

Yarivette

I was taking birth control pills for almost four years. On Dec 15th Was my last period day and last pill. I’ve been having unprotected sex with my husband and now I’m 5 days late. I’ve been dizzy and nauseous, my breast are bigger but not sore. Also I’m a coffee person but lately i can’t stand the smell or taste. I’m bloated, i’m having cramps and may back hurts A LOT Could I be pregnant? How long do I have to wait to take a test?
