Ovulation

So I’m pretty sure I ovulated on the 17th bad cramps on left side and spotted some blood. That was off and on that day. The 18th was the same a cramp pulling feeling on my sides. And today my ovulation test was completely negative now. I never reached a peak on my test but I’ve read that you don’t always need to reach “Peak” to ovulate.

Has anyone else ever had spotting then pulling feeling on left or right side and ovulated? I’m just wondering who ever else felt that.
