I missed one pill in the last week of a pill pack but continued to correctly take the next 5 active pills. I had unprotected sex on the Friday of that week (last day of the active pills), and then the following week I had the usual withdrawal bleed.

Is it possible I could have fallen pregnant because of the missed pill? It's now 4 weeks later, if I was pregnant would it show up on a hpt if I tested now?
