Bulimic on the pill

I was bullied for my weight and I recently stopped being bulimic once I got help I was always relapsing so recovery never lasted for long. I’m at a healthy weight now and I started my birth control pill 3 years ago and I’ve been bulimic for a year. This month is when I relapsed but I got help two weeks ago. I always threw up before taking my pill. I take my pill at 10 at night so it can be absorbed and I usually purge from 12-8 pm the next day . I have never thrown up a pill or missed a pill. I’m afraid that I messed with the effectiveness of my pill. I am sexually active and my boyfriend pulls out. Please do not judge me I am receiving help and because I do not want to get pregnant I’m taking it seriously to not relapse but I didn’t think about my pill since I’ve never thrown it up. Please help and calm my anxiety or share your story I’d appreciate it.
