Ovulation discharge

Miranda

I got up this morning to pee and I had a watery stretchy like egg yolk discharge and I didn’t test because I thought I may have missed my ovulation so once I saw that I drank a lot and went to pee and it’s like my watery stretchy discharge got like thick and sticky and i tested and it was a negative ovulation I’m confused why would I have the ovulation discharge and it change and not get a positive test
