I have looked into this a little bit, but I haven’t found a exact answer yet. I thought maybe I’d ask on here and see if any of you know. I was ovulating from the 1-8, and on the 8th I had the worst cramps I have ever had in my entire life. I went white and they were in my back. It felt like I was going to pass out. I was thinking implantation cramps, as I had sex all days 1-8, but what I’m seeing is they happen 2-7 days before your period. Maybe my hopes are just up. Has anyone ever heard of this during ovulation?
