7 days of flashing smileys on clearblue digital advanced

Mary • 37 yrs old and just gave birth to my rainbow baby 2/22/17 after having had 6 losses and I'm expecting again on 2/9/18
Ok as the posting title has read,ive had 7 days of a flashing smiley. Its my first month using these tests. Dr said 3 days after my positive to start progesterone. My cycles have varied since my loss in November. I started testing cd 6 just to be sure i dont miss my surge. Well....i havent had my surge yet and im getting concerned. Is this normal with these tests?
