Eating pan?

So my brother made me mac and cheese cause he's the best. anyways i thought he put maybe a tiny bit of pepper on it cause it had a little bit of black dots on it. then half way through eating it he told me he didn't put pepper on it and that must just be the pan coming off on the mac and cheese. i immediately stopped eating it. i'm so stressed now. i'm 25 weeks pregnant. is my baby gonna be okay? there was barley any on it just still scared
