Possible weird symptoms?

Kate
I ovulated last Wednesday. My husband and I are TTC so obviously we tried. On Saturday I had very light spotting with a small amount of brown blood or mucus. Then for the past 3 days my hips have been killing me. Every once in awhile I have a very slight dizzy spell. It passes quickly though.  I didn't have any of this when I got pregnant with my son but that was 5 years ago. Has anyone else experienced any of this?  Could it be very early pregnancy symptoms or am I just wishful thinking?  It's too early to take a test but I really want to know that this is normal.
