I made a mistake

So this if going to be really dumb and long but i’m having really bad anxiety about it and I guess I did it to myself but if any of you have advice I would appreciate it.

I’m 18 and my boyfriend is a few weeks away from turning 19 and we’ve been together for about 4 months.

Normally I’m on birth control to regulate my periods bc I’m anemic and before my periods were irregular and very heavy. Well at the end of December and beginning of January my doctor wouldn’t fill my prescription for birth control until I made an appointment, and I was on break for college and I kept (this is my mistake I should have tried to do this on my own) asking my mother to make my appointment. So I hadn’t been on birth control for all of winter break but that was going to be okay bc when we aren’t at college he lives 6 hours away.

Well he surprised me and got plane tickets down to where I live and we got to hang out for a few days before he had to go back home. Well since I’m normally on birth control we don’t use a condom since whenever he tries to wear them they shrink and ride down so we just avoid that situation by not using them and relying on pull of for the secondary method (which has worked perfectly before bc he’s never not pulled out in time).

Well he hadn’t brought condoms with him bc we never use them and I trusted his judgement for pulling out because I had been torturing him on Facetime and I wasn’t about to tease him and then when he got there not let him have any (this isn’t like I wasn’t down for sex I totally was and I was 100% into it).

So we had my house to myself because my brothers were doing stuff at their college for the day and my parents were at work. Well I forgot my dad had a lunch break and so we are having fun and he’s just finishing me off before he lets himself finish by teasing and other stuff. Well my dad opens the door and starts talking to me (the lights were off and I don’t have a window in my room bc I’m in the basement) so I freak out and do this really quick turn to talk to him, and my boyfriend was on the edge of his own orgasm but he “wasn’t done letting me orgasm” so he wasn’t letting himself go yet, but after I did the turn in the bed he came because I guess it took him over the edge and he couldn’t stop himself.

Well he pulled out and came on my thigh, but it was really close to my Vagina/ labias and stuff. This week my period was supposed to start on Sunday, but it’s now Tuesday and it still hasn’t came. I don’t know if my boyfriend got me pregnant or if my body went back to unorganized periods where they happen whenever they want but I’m scared I have no idea what I should do.

I know I don’t want to have a baby and my boyfriend doesn’t either. Should I take a test? Maybe my period hasn’t come because I’ve been so stressed and anxious so my body won’t do it. If you have any helpful words please help me.

TLDR; Boyfriend and I had sex without any kind of contraception except pull out. He told me he pulled out in time and I didn’t feel any cum in my vagina but worried if I still got pregnant because of where it landed outside of me.
