Anyone have this happen?

So I am on birth control, but I missed three pills about a week after my period ended and then started bleeding again. The bleeding lasted about three days. My husband and I had unprotected sex all week including the days that I missed the pills. Has anyone ever had this happen and then end up getting pregnant? I’m just curious. We have been planning on going off of birth control, so I just don’t really know what the bleeding means after skipping those few pills.
