Help ! Lol Seriously my body is playing tricks on me!!! 🙄

So I ovulated on CD21, (day of the NY blizzard Jan 23rd) last month I had a 32 day cycle... Today marks cycle day 32 and no period. Yet a negative pregnancy test this morning , I've had Lower back pains, cramping, 3-2 days ago like the smallest amount of brown spotting so minimal... (Def not any sort of period) So do you think it's possible I just haven't produced enough HCG yet since I ovulated later than normal? I legit spiked the pregnancy test into the garbage this morning like it was a football when it said "not pregnant" 🙄😁
