Possibly Pregnant?

Hello ladies, so I was supposed to have my period on the 11th of July I went to wipe that day and it was only one medium sized spot on the tissue, I haven't bled since, I have had a lot of symptoms of early pregnancy more than I get with my period, I took one test when I was 2 weeks past my period and it was negative, however I'm still experiencing symptoms and still haven't bled, my breasts have been sore this whole time and I have also been nauseous this whole time and I have also been craving foods I dont generally crave, I plan on taking another pregnancy test on the 11th of August as I will be one month past, if its negative again I dont know what to do
