Pregnant or not?

Tishera • Married Mother of one and planning for another!
I need help, I been on the IUD for bout 2 years, and took it out earlier this month, had sex almost everyday on my fertile period including the highest day. Anywho, I'm two days late spite some extremely lite spotting but am testing negative. Earliest Doctors appt is bout 3 weeks away. Do u guys think I could be pregnant? Or is it just wishful thinking?
