What is this???! TMI TMI TMI

Hi all. I'm on CD 34. I don't know when I ovulated. All I know is this is the longest cycle I've every had. Today I go pee and I thought my period was finally coming on. When I wiped, the tissue was as clean and white as the driven snow. So I put on some white panties to make sure I'm not missing anything. Nothing really, no red no brown... I got a negative hpt this morning. Is this my period? Am I preggy? Am I imagining things?

Side note: it's definitely not shit. Lol
