Could I be pregnant?

Hillary
Hello All! So my fiancé came home from Kansas on the 18th of May (he is military) and we had sex 18,19,20,22,23. I had my nexplanon removed on the 25th. My period was due on the 23rd but never came on. While on nexplanon my period ALWAYS came on. I would even have a period twice a month. I asked the nurse was pregnancy possible and she said yes. Just wondering if anyone else has gotten pregnant after this type of situation.
