I'm confused , help

My first last menstural period was on the 1/13/2016 lasted 4 days , I conceived 22-24 , I don't have a missed period yet .. But I've been feeling hungry a lot , nipples sore,  nauseas , dizzy, tired , I spotted just a tiny bit I think on the 29th of Jan. Ughh I'm so moody and anxious , I took a pregnancy test on the 1st but it came out negative I am assuming is bc the HCG level is extremely low and it's too early to know , should I wait till my period is due or can I retake the test again and in what day? Please help I'm anxious and I am trying to get preggos🤗 I'm going threw my fertility chart an I just hope I am.
