Please help, I’m so confused 🤷‍♀️😩

I am exactly two weeks late today; I did a couple of pregnancy tests last week they was negative and I’ve done one this morning also negative. I had sex on 25/12/19 and was due on 30/12/19. Would it be too early to detect as if I was pregnant I would only be just over 2 weeks? 🙈 thank you x
