Brown spotting

So, here’s my ovulation tests from 11/23, as you can see the bottom test taken at the end of the day is as dark as the control line. I had taken Clomid 100 mg this past cycle before the tests. I believe I possibly ovulated over night because the test the next morning is slightly lighter, just a smidge. IF I ovulated on 11/23-11/24, then I’m 13-14 DPO. I took a pregnancy test two days ago, negative. Yesterday, I started having brown spotting. Same with today. My period isn’t due for another 5 days. Thoughts?
