Spotting in between periods.

Tina
Last month I was 10 days late. When I took a yest it said negative and started hours later. We've been trying for 3 years now. My husband got checked and everything came back ok. Now my ovulation track is off cause ive never neen this late. I started spotting last weekend and now really light spotting today. Is this just something prior to ovulation? Just weird to be spotting 2 x in less than a week.
