I Took Clomid Last Month, And AF Was Due Jan

I took Clomid last month, and AF was due Jan 8th. When I was 2 says late, I took a HPT and it was negative. I thought I was having pregnancy symptoms, tho. Nausea, increased urination, fatigue, and tingling breast. I'm 4 days late today and I am having some spotting. Called my gyno yesterday and today and haven't heard back yet.
