Help..😔

I gave my boyfriend a blow job and after I swallowed I kissed him but about 45 minutes /1 hour later he ate me out and fingered me yesterday it says my fertile window is suppose to start in 2 days from today.. for some reason the thought of me being pregnant came into my head and ever since last night I’ve been freaking out it’s all I am thinking about, al I want to do is cry and freak out, my bf tried to comfort me and said that he really thinking that I’m fine and that I shouldn’t worry about it, but I have really bad anxiety and I can’t help but freak out about this..😢 ido what to do I’m going insane
