What is this?

Sorry for the detailed and TMI picture. I’ve been having this kind of discharge on and off for about week. I’m just finishing ovulation week. I’ve been sick this past week and had abdominal pain to find out I have a 10cm cyst on my ovary. And this type of discharge literally pours out of me. No odour, no itching or burning. I have no other symptoms. Can anyone tell me what may cause this? It’s watery but yellow...
