PLEASE HELP!!

I made a mistake and had sex with my boyfriend 3 days ago. We had no protection but he pulled out. He also only went halfway in. We had sex about 4 days before my period is scheduled to come. All of my apps say that I wasn’t ovulating when we had sex because it was only 4-5 days before my period is scheduled to come. This was my first time having sex as well. My period is scheduled to come within the next two days but I’m so scared. I’m not going to mention my age out of fear of judgment but let’s just say I’m way too young for a kid. Someone please give advice or just tell me my likelihood of being pregnant. please help!!
