Early period??

Jodie • IVF warrior - Expecting our rainbow April ‘23🌈🌈🌈

My period finished 8 days ago and I’m due to Ovulate tomorrow, I decided not to temp or use OPKS this month and take a more relaxed approach, for the past two days I’ve had light smudging/spotting and last night it got heavier. I went to the toilet today and I’ve got my period!! Is this possible??? Could it still be old blood and there’s a possibility I could still be due to ovulate??
