omfg help

so i’m petrified. i’m going to the doctors tomorrow for multiple reasons. i was initially gonna go to ask about the pill and blah blah but now i have an even bigger worry. the last time me and my boyfriend had unprotected sex (pull out method) was about 3 weeks ago. NOTHING WENT IN ME, he came after he pulled out. ever since we’ve had protected sex but also used the pull out method just to be extra careful. i’m meant to be on my period now.. in fact i’m a day late. i am having extreme lower abdominal pains, my vagina is aching like fuck and i’ve got small dosage of discharge, my lower stomach is swollen and hard. BARING IN MIND IM FUCKING 16 AND STILL IN SCHOOL. im freaking out. what’s the likelihood of me being pregnant? if i am, i’m not gonna get rid of it bc i don’t believe in that. i told my boyfriend and he’s coming to the doctors with me bc he’s kinda hoping i am but not at the same time. my friends thought i needed a shit so i went for a shit and the swelling went down and the pain isn’t as bad but honestly, it hasn’t changed that much. IM SO SCARED AND IDK WHATS GONNA HAPPEN IF I AM I JUST NEED TO KNOW WHETHER ITS LIKELY OR NOT AHHHHHHH 😰 please don’t judge btw, i know i’m stupid but i do actually love my boyfriend so so much, like i see a full future with him so it’s not like i don’t trust him and he’s completely understanding about this whole thing, it’s my parents i worry about most tbh...
