Yea I was the same way and mines came out negative then a month late I'm feeling sick I took a test and it was positive it shocked me lol
Wait longer then take a test or go to your doc that's the best advice anyone on here can give you. Home prego test arnt always accurate keep that in mind as well your doc can do a blood test and get a moreacaccurate reading
I would wait until after you have missed your period so usually around 14 days or so. I took mine the day after I missed my period and it was positive. :) good luck
