Help guys!

So me and my partner are TTC, and my last period was from 13-19th of May... The last time we did it was on the 6th of June... And according to the calendar, my period was supposed to come on the 13th of this month...So it's late for almost two weeks now... Yesterday I felt sick all day, so today I made a pregnancy test that came out negative... I've been feeling really tired, and every time I lay on the sofa I just fall asleep... I just don't know what to think... Opinions please. Am I being too paranoid? Or just the anxiety is making me like this? Cause I could swear that I am pregnant... I don't know 😱😥😥😥
