To begin with my last period was Oct 12 and I had an iud removed on Nov 2nd. My partner & I had sex the next day without protection and still no period yet. Could I be pregnant?

Sure you could be... any time you have sex it's possible... especially unprotected sex.

However, the real question isn't could you be but are you... and there is no way for anyone online to tell you the answer. You'll just have to wait and see if you get your period.
