Hi ladies!!

I'm super confused on the 30 I had brown discharge then on the 31 I had dark brown discharge so I taught it was AF that had shown it went from dark to light it only lasted 4 days. I took three cycles of clomid which made me think that maybe that's why it was that color I called the doc since I don't hav an appt til the 16 he said that it wasn't a normal period since it only lasted 4 days so that confused me even more I taught anything after 3 days it is I guess I was wrong? My question is has this happened to anyone before I'm so confused
