Urine trap or positive ?

I had sex the 11th , 17th , 21st , and 25th. On the 25th i ended up spotting which progressed into a “period” with clots the 26th - 27th but stopped completely the 28th and on the 29th I just spotted for an hour and then nothing. This is unusual because my periods are always 5-7 days and heavy. Ever since my “period” ended I been experiencing nausea , sore and tender breast that has gotten more heavy, bloating and cramps. I been testing since and have been negative until now ? I’m not sure if this a positive or not. This line came up within the frame almost immediately ?
