I had sex for the very first time yesterday He

Patient: I had sex for the very first time yesterday. He wore a condom and he came inside of me. He checked afterwards if there were any tears and there weren’t. I am not on any form of birth control. After he left I looked on my period app on my phone and it said that I had a high risk of pregnancy because it was the day before my ovulation day. I told him and he bought plan B. I took the pill an hour after having sex. I experienced a headache and slight cramping last night. I am extremely worried. What is my risk of pregnancy?

Doctor:
