Pregnancy scare

Hi, I’m a 15 year old girl and i’m scared I might be pregnant. He didn’t cum inside me he just had precum but that can still get you pregnant, I keep feeling like my stomach needs to like rumble all day and my boobs have been a bit tender and I’ve had sharp vagina pains. I’m really scared, my periods due in 9 days so I can’t take a test yet. Thank you.
