Am i pregnant?

I know i can't know for sure if I am with out a test. But I'm just asking for opinions.

My period is late by 3 days. And I'm anxious. I had sex 2 days before my fertile window and it said i had 7% of getting pregnant.

Still we use the withdrawal method (i know it isn't that good but God I'm 15 AND I KNOW IM STUPID...) still he didn't cum inside of me.

I'm really anxious and nervous too.

I don't have any cramps

I ain't tired or extra hungry either

I ain't bloated

I had a little of diareah ( I always have before my period starts... but it hasn't stared)

And I haven't even spotted a little

Still i don't have like any real pregnancy symptoms.

But idk what do you people think I guess?
