Clomid questions

Christy • Husband and I TTC baby#1 for 5 yrs! 29 years young!
I started clomid on Tuesday and I did not read anything about it changing my period. So my AF is always 7days long and very/extremely heavy for 4-5 of those days. Yesterday and today it's been the opposite Very light. Is this normal had anyone else ever experienced this? 
  PS hot flashes are not awesome!
