I have a 27-31 day cycle and usually ovulate (based on pains and Cm rather than opk’s so could be a day or two out) around CD15/16. On CD10 I had a mild twinge/cramping type pain on left side which lasted a few mins then CD11 I had one small amount of EWCM. Today is CD12 and nothing. I usually get around 5-7 days of ovulation aches and cramps. Is it possible I ovulated early with unusually minor symptoms or just my body gearing up for my fertile period to begin in a few days?
