New to this!

This month I have forgotten to take my birth control pills a few times. Monday night, I had taken Thursday's pill, so I was about 3 days off (I have never been that bad off, it's been a crazy month) Tuesday night, my husband and I decided to start trying for a baby. I had one pill left, but was so excited I just quit taking it. I'm supposed to start my period today or tomorrow, but showing no signs. Basically I'm wondering if it's possible for me to either be pregnant from being off on my pills last month, or could I be ovulating from stopping the pills. I'm new to this!
