Waiting Game

This is going to be the longest week of waiting ever. My fertile window supposedly started the 24th of March and goes through the 2nd of April with possibly ovulating tomorrow the 29th according to my app. I think I may already be ovulating not sure though. Yesterday I started cramping kind of like period cramps and twinges in my lower abdomen. I just had my period the 17th & 18th of March. Could this be cramping due to ovulating or conception possibly? I have been taking Evening Primrose Oil for the past week and using Pre-Seed lubricant. What are your thoughts ?
