Ladies on Clomid!

Amy • Married to my best friend since 2007 TTC our first since September 2014
This is my second round of clomid. The first round my period came a little late, on CD40. My average is 34 days. On this round, I started to spot today on CD 30. I haven't had a cycle that short in 10+ years! It's not a full flow yet but I'm sure it's coming. I just ovulated 9/10 days ago. Has clomid changed your cycles? Shorter or longer?
