Removed IUD late sept, no period yet?

Glow said originally I was supposed to start period October 1st. And now it's the 12th and still nothing ? My SO and I had unprotected sex the night I removed the iud and multiple times since then and I have no real signs of period. How much of a chance is there that I can be prego ?
