Help!!

This app says my ovulation was yesterday. But today I got slight cramping in the left side then about 5 minutes after that I got a massive lot of thick, white cloudy type discharge that was a little bit sticky. So I thought I’ve just started ovulation., and since then I’m getting slight cramping that goes from both sides, then just my right side, then just my left side. so I went and brought some ovulation tests and it’s came back negative. :( I’m really confused.. please help
