My period is late

Les

My period is currently 5 days late and I’m starting to panic. My boyfriend and I have used a condom every time but I’m not on birth control yet. I’m only 18 so I’m freaking out right now. I’m going to get a pregnancy test today and check but I’m so scared I had a panic attack and nearly vomited the other night. I have been experiencing a lot more stress than usual these last couple of weeks and I’m praying that’ll be the cause. Does anyone have some advice?
