My daughter had sex 2 1/2 weeks pp

So I just found out my daughter had sex while she was only 2 1/2 pp! I’m honestly pissed at her irresponsible actions when she knows that sex too soon can cause numerous of things to go wrong, especially an infection as she’s not fully healed! She has a doctors appt later this week to get checked since she decided to have sex so soon! She said she was still spotting as well, is it a chance she could get pregnant considering she was still bleeding when it happened? She’s my only child so I’m not too familiar with how soon pregnancy could occur!
