I'm a little confused..

I have been tracking my ovulation on the days that its closest to my ovulation but a few days ago I get some weird cramps and I got some light spotting before my calendar even says I was supposed ovulate so I took a test. the first one was that day, the second was the day after and the last one is from today, the last test I skipped a day after the second and took one today. I'm supposed to start my ovulation week this week starting with the last test, can anyone tell me if I already ovulated.. or

what's happening here? P.s mind the markings on them I messed up lol
