Am I pregnant

So I went to my OBGYN on tuesdays and since I’m under 21 I couldn’t get a annual but I also went to get put on birth control. The one I choose was the IUD and I have to be on my period so they can insert it. I took a urine test that day so if I were pregnant I would’ve heard back and my period was suppose to be here yesterday according to this app ik sometimes it changes but like I’m getting all my normal symptoms and it’s just haven’t came yet and want it to hurry up since the holidays are around the corner and my doctor might not be in
