Am I pregnant but testing to early?

Backstory first: I was on depo for several years and decided it was time to try. My last shot was in March and my period came in early June. I have been testing ovulation and had a peak test on July 17 and me and my boyfriend did the deed that night and 2 nights later. July 23rd I started spotting and did for about 24 to 48 hours then stopped. I am now exhausted all the time and my boobs started hurting today along with having thick white discharge “down there”. But when I take a PGT they come back negative. Am I testing to early or am I just giving myself imaginary symptoms.
