Emergency❗️ IM FREAKING OUT

Yasmin
Ok so yesterday me and my SO were having sex when he came inside of me. He's freaking out and apologizing every second. But that's not the point. What I want to know is when should I take a pregnancy test to find out. I keep hearing 10 days or 3 weeks, but I want more opinions. I'm freaking out and I'm trying to stay calm. If you all could help that would mean everything.
