How soon can you feel pregnancy symptoms or take a test? PLS help.

I’m usually on birth control but it wasn’t filled for like two weeks so i went without. my bf still pulls out even when i’m on my pills regularly, but yeah. we had sex twice once maybe a week ago or a little over and again a few nights ago, and both time i was on top when he finished. so this makes me nervous that he didnt pull out on time. he’s the time to worry a lot if he thinks he didn’t but he never said anything about being worried these times so idk. But i’ve been nauseas a lot but i deal with nausea pretty frequently anyway so i could just be freaking myself out. but now i’m having kind of like a cramping feeling in my lower stomach pretty much where period cramps are. but feels a little different then a normal period cramp. and i shouldn’t get my period for like 2 more weeks. And i also just saw the days we had sex were a few days before my ovulation day and my tracking says high risk of pregnancy :( is there any early signs i should look for? and how soon is too soon to take a test? i know you’re suppose to wait till after your missed period but obviously i’m kinda freaking out. thank u so much in advance.
