pregnancy scare is killing me

Problem/Goal: my partner and i had sex unprotected and i know to myself that i finished outside, but theres that doubt in my head thats telling me negative stuffs

Context: her period just finished to be specific on the 23rd of jan and we did it on the 25th of jan i searched around the net and it says that its a low chance but i keep overthinking all this what ifs, but i know to myself na i finished outside but i did some research that sometime you wont feel you finished but actually did. so this feeds my negative thoughts some more and its keeping me up at night and i can't imagine what my partner must feel rn. we talked and asked her if she felt like something warm or hot while we're doing it and she said no so i was relieved but theres still this doubt in my mind thats telling me that things will go wrong. like what if it did go wrong? i need some advice or some similar experience that you experienced i attempted to buy plan b but my partner stopped me and told me to calm down first i really need advices

Edit: thank you po for all your inputs, will make sure to take your advices po, please pray for us 🥲
