pregnancy odds?

i had sex 6 weeks ago for the first time. we fooled around a bunch & he owed like twice before we actually had sex. when we did he pulled out and he came on my stomach. i didn’t know when i ovulated so i took EC a few hours after this. turns out via predictions on the app i was just starting my luteal phase and should have only had a 3% chance. i’ve had bleeding that’s been heavier than spotting and for multiple days but its shorter than my normal period. a few days ago - a little over a week after my last period - im experiencing pretty heavy spotting/bleeding(?) it doesn’t collect a lot in the pad but mostly when i pee or wipe it’s heavy. no positive tests and i’ve taken a lot of them. any thoughts or advice would be helpful.

i know a lot of this situation is not the smartest but it was my first time so i’m extra freaked out right now. please be gentle.
