Ovulation cramping?

Hello ladies! I've been TTC for a little over a year now. In February 2018 I had an ultrasound done and I had or I have a 2cm cyst on my right ovary. The doctor said it should pass with my next menstruation which was March 6-10. According to the app I in my ferile window and due to ovulate the 23 of March. The past three days I have had very very light faint pink spotting and today I am cramping in what seems to be the middle of my uterus. Does anyone know what this means?
