Ovulation bleeding

Sammi
Does anyone else have heavy ovulation bleeding ? Its not light and pink as it should be its heavy like a period and lasts maybe 4 hours. With slight cramping and then stops . it only happens on the 3rd fertile day during ovulation......... I dont get it. I dont know if this will hinder my chances of getting pregnant or not but I am bringing it up to my obgyn when I see her next.
