Where’s My Period?

My periods do today and I’m 16. I’m getting really nervous cause I’m worried I could be pregnant. I’m on the birth control pill and I’ve never missed a pill and I always take it on time. My bf and I recently started having sex without a condom and he pulls out way before he cums. Today I’m on my third white pill which is usually when my period comes and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period is due today but its not here yet. I’m getting really paranoid. Do u think I’m pregnant??

Edit: got my period :)
