Did clomid affect your period?

Hey! This is my 2nd month off clomid. My first month was a pretty normal period and now this one is way different. I'm 6 days late, boobs hurt very bad, I'm having heartburn, light cramps. I'm wondering if clomid is doing this and has it happened to anyone else? OR could I be preggo?!? I've taken tests and all negative.
