Serious question

Usually have really heavy periods, but I’m on the 6th day of only spotting. All tests have been negative and I did my first round of Clomid last cycle. It’s to the point now where I only spot when I poop, and yes it’s vaginal bleeding and not the other. Any one else have this? It’s really weird. I don’t strain or anything. The last few months when I did start my period it started when I pooped and then was just my regular period. I started my second round of Clomid yesterday since my tests have been negative.
