I need eyes

So I had a weird cycle of u can call it one... February 6th was when I was suppose to get my period but I missed it...I took a cheap pregnancy test n I thought It was negative. .. that day- i spotted pink and dark brown when i wiped 3 times that evening so i put on a tampon and went to bed i thought here we go and the next morning i took it out and nothing was on it clean as when. I put it in and now it's suppose to be my 3rd day and still nothing .

THIS IS THE SAME TEST JUST NOW THAT I WAS LOOKING AT MY PICTURES I TOOK THAT DAY FEB 6TH I THINK I SEE SOMETHING...PLZ HELP
