Scared Asf Right Now !

I Know I’m Probably All In My Head Right Now But I Am Terrified That I May Become Pregnant . I Had Sex Last Friday and I mean neither one of us cummed and I don’t remember seeing any Pre-cum. Brother couldn’t really get it up , honestly 🤦🏾‍♀️🤷🏾‍♀️🙄 But For Some Reason i Have So Much anxiety. He tells me not to worry nothing will happen but I can’t help it . I already have a 3 year old... I’m Not Ready To Start over the process again
