2 Days Late

So I am currently 2 Days late , which never typically happens but also a senior in college so I’m thinking stress🤷🏾‍♀️. I took a First Response Early Detection Digital year on my first day and it said no can anybody tell me how accurate these are and when should I test again? Pregnancy isn’t in the plans right now for my boyfriend and I lol but best to know what’s going on!
