Bleeding on Ovulation Day

Hi there..need some advice and thoughts..im turning 42 this year ttc for 3 minths with irregular cycle. Just had pap smear and cervical examination and everything looks fine. Hormon imbalance is my main problem which resulted with my period became prolonged and sometimes short. I had my last period which ended on the 13th and supposedly my ovulation day is on the 19th but instead of having an ovulation i found a red spotting which is light in colour and very thin seems like it is mixed with water..it's been trailing on till today..what could it be..? Can anyone share me some thoughts..? Tnx..
