Hi, I had my IUD removed on October 28th. I did not start birth control right away, we had sex on Nov2, and the 5th. We have decided to have a baby. How long would it take for me to know? Would we have conceived on the 2nd? ( Obviously if egg was fertilized ) I have 3 kids from my first husband... but now I feel like I cant remember the steps. I know its only been week, but is it possible to be pregnant that soon after IUD removal?
