Confused Lh

Hi ladies I'm confused I started spotting the tiniest bit just one. The next day I start getting symptoms like my period is going to start and I still do think its coming any time soon. But i decided to test for ovulation and what do you know! Positive ovulation strip! I think it's the first time I had ever seen a blazing positive. I wonder why I feel like my period is coming but I'm positive for ovulation?
