Is my relationship going to end?

My (18) girlfriend (16) and I have been dating since high school, she’s a junior, she’s just the youngest in her grade, I already graduated recently, we ended up spending some time at my place and things got frisky, we had sex and of course in the heat of the moment forgot protection, she thinks she’s pregnant after we did it, I bought her birth control but her anxiety is telling her she’s pregnant and making her distance herself from me, she says she feels uncomfortable around me now, and she won’t talk to me or anything, I send her messages every now and then just supporting her (ex. Hope you’re doing amazing, please make sure to eat something today my love, etc.) am I screwed? Is this relationship over? We’ve been together for a year now and I really love her, she’s an amazing person and she used to feel the same, but now I’m not sure, I’m scared of losing her.
