Who is on clomid

My first round of clomid went good I also took provera to have my period and my second cycle of clomid went good too but this 3rd cycle I didn't take it because I haven't gotten my period ever since Saturday I have brown stuff coming out of my vagina but only when I wipe and its only been Saturday and Monday I think its not normal. And I'm worried cuz I don't know what's going on I also did take a pregnancy test but its negative you can see a very faint line but I'm also waiting to retest
