My first positive opk in my 3 months since starting ttc!!

Ok so I was always regular with my cycles up until May when we decided to start trying. Then...... everything f****d up! But today I finally get my positive. Iv got slights cramping about 9pm last night and it’s came and went today also and this happened. I’m so happy as I thought I was broken.

Is it normal to feel ovulation cramping the day before getting positives? Iv never paid attention to ovulation obviously before ttc but I can remember getting these twinging feelings and now I know why.
